  • VertEx
  • Can I see an AirBench in operation?

    No obligation on-site demonstrations are available across the UK, alllowing you to view AirBench in operation on your own dust or fume problem. Contact us to book (use the form below).

    Alternatively, we always welcome visitors to our factory and recommend this for buyers considering our VertEx or RP ranges.

  • How long is the warranty?

    12 months as standard, with any required remedial work being carried out on site, or the unit returned to our works – at our discretion and our cost. We have a very low level of warranty call-outs, at less than 1% of our production.

  • Can I have a 110v AirBench?

    Most models of AirBench can be supplied configured for 110V supply. We have several different options for conversion; contact us to discuss the most appropriate.

  • Does AirBench comply with COSHH and HSG258?

    Every AirBench complies with HSG258 (click here for more information from the HSE website). Each unit is fully tested and commissioned before shipment, and a commissioning certificate provided. Real time performance monitoring is possible via the integral filter pressure gauge, allowing simple forecasting of filter life. To discuss HSG258 in more detail, contact us.
    When correctly specified, AirBench allows you to comply with your obligations under COSHH.

  • Do prices include delivery / installation / offloading?

    Our prices include delivery within mainland UK; onwards delivery is charged at cost.

    We do not include offloading, positioning, or installation as standard – in general installation simply involves plugging in to a 13a socket.

    All our units are workshop run before despatch and are supplied with a completed commissioning certificate, in accordance with current HSE guidance.

  • How long do the filters last?

    Disposable media pads should be changed at least monthly.  Most other filters will last 6 – 12 months generally.  In heavy use this may be less; ask us for guidance.

    For high volume applications, consider our RP model with self-cleaning filters.

  • Can I clean the filters?

    Most dust filters can and should be cleaned. Fine filters and carbon filters cannot be cleaned, and should be replaced when full, damaged, or end-of-life. Disposable media pads used in certain configurations cannot be cleaned.
    Generally the most effective method for cleaning our standard filters is with a vacuum cleaner by removing the surface. Our RP units include filters which are cleaned by reverse pulse air using an external air supply and are designed for high volumes of dust, although only suitable for certain applications.
    All filters will need changing eventually – ask us about estimated filter life for your application.

  • Where are the filters?

    Immediately beneath the surface in most models (EX, FP, FN, FPK types). Filters are generally interchangeable allowing you to update your AirBench to an alternative specification if required.

    In the FPW and FPT ranges the final filter is housed in the box to the left hand side and is accessed through a removable door.

    In the RP range the main filters are again beneath the surface but are removed for changing via a removable front door.

  • What filters do I need?

    Call us; we are always happy to recommend a model and filter set. For most applications we have standard models to suit.
    Alternatively, use this site to navigate to a suitable model – just find an application similar to yours, then choose the construction type from the table of available models.
    Our standard configurations cover most applications; if your application is not listed please ask.

  • Are there additional costs?

    The only ongoing costs for most AirBenches are filters, and electrical supply. Most units run on a standard 240v single phase supply, at relatively low powers (typically <500w); and if you call us to discuss your application we can give an estimate of ongoing filter costs. [/av_toggle] [av_toggle title=’Can I have fine filters?’ tags=’Filters, Technical’] We offer filtration to H12 HEPA grade; however, over-filtering will cost more money to buy and replace. Our standard filter configurations have been designed and proven for almost all applications. Call us if you would like to discuss the correct selection. Most of our filter configurations are interchangeable – it is generally straightforward to upgrade filters at a later date if required.

  • Do I need wheels?

    Wheels are useful and are available on most models – but AirBench is easily moved on a pallet truck. If you are only likely to move your AirBench on rare occasions, don’t buy wheels.

  • Do I need ducting or an external exhaust?

    No. AirBench is self contained. If required, we can supply AirBench configured for connection to your ductwork, at no additional cost. Ask us for details of ducting requirements.

  • How do I clean the filters

    Using a vacuum cleaner or by removing from the unit and emptying into a bag – wearing appropriate PPE of course.

  • Is PPE required when changing filters?

    We would recommend the use of PPE when handling contaminated filters.

  • Can I have one in 110v?

    We do not currently offer a 110v unit.

  • Who are you?

    “We are part of AirBench Ltd, one of the UK’s leading fume and dust extraction equipment manufacturers.

    In mid-2014, Air Cleaning Systems Ltd, the manufacturers of the OMF range, went into liquidation. AirBench Ltd acquired this (successful) range from the liquidators, and alongside selected team members from ACS have reintroduced the product to the market.”

  • How do I clean the filters?

    “When Filter 1 is full it can be cleaned.

    For the best results apply a degreaser to the dirty face and allow to absorb. Rinse, applying the process to the top of the filter to allow the dirt to be washed out downwards. Allow to drain until dry.”

  • How much are replacement filters

    Contact us for current pricing.

  • Do you offer a servicing contract?

    If you would prefer a service contract, contact us to request pricing.

  • Is PPE required when changing filters?

    Yes. You should wear PPE when working with coolant.

  • How long will the installation take

    We would estimate 1 day per filter unit, including wiring to your machine tool.

  • What wiring options are there?

    Either connected to a standard supply and controlled using the rotary isolator on the front of the machine; or (more usually) connected to your machine tool by our electrician, so the OMF unit runs while your coolant pump is running.

  • Does it need a single or three phase supply? What voltage?

    We can offer a single phase unit using a highly efficient fanset if required. Standard units are three phase; either 230 or 415v as required to connect into either your mains supply, or your machine tool’s main board.

  • Do you install?

    Yes, we have fully trained and insured installation partners.

  • Can I install myself? Is there an installation kit?

    You are welcome to install and we will ship the OMF with a complete ducting kit for your machine.

  • Can you connect ducting to the outlet?

    We can provide fittings which will allow this although most units discharge back into the workshop.

  • Can it be wall mounted?

    Yes, although usually only OMF500 is small enough that you would want to do so!

  • Can the sump feedback into my machine?

    On OMF500, yes – the sump can very simply drain into your machine. For larger units, the sump would usually drain into a drip-tray. This can, if required, be pumped back into your machine.

  • Can two machines be fed into one OMF unit?

    Only in certain circumstances; OMF filters are selected to suit a certain size of machine tool.

  • Can I join 2 or 3 in series?

    Usually, specifying the correct unit avoids the need for this.

  • Is the ducting leak proof

    If well fitted, yes! We use only high quality clip-together ducting from a leading specialist manufacturer.

  • For our risk assessment protocol is there any fire risk?

    For coolant – no more than with any other machine. For oil mist, discuss with us.

  • When you are accessing my CNC, are you insured for damage

    We are fully insured and will not undertake any work on your machines without your prior agreement.

  • What is your delivery time

    We can usually deliver a unit complete with ducting in under 2 weeks – faster if you are in a rush.

  • Can you colour match my machine tool

    We can usually match colours; there may be a small charge for this.

  • Can it be machine mounted

    “OMF500 can be machine mounted. Larger units should be floor mounted.

    Note though that machine mounting means that you have to claimb a ladder to perform any routine servicing! Locating the unit next to your machine tool means that operators are not working at height while handling filters.”

  • How long will the filters last?

    HEPA filters last typically one year. First stage mist filters, with care, can last several years.

  • Can there be an audible filter full alarm?

    This is possible, and would be a costed option. However, in most cases it is not necessary; the large face gauges on the front of the machine provide ample indication of filter condition.

  • Can the doors be hinged on the right?

    If needed, yes.

  • Can it deal with oil mist

    With the correct filters, yes. We offer two filter types; type ‘C’ is suitable for coolant mist (emulsion) – type ‘O’ is for oil mist.

  • What are the ongoing costs

    Mainly filters. Contact us to discuss likely filter costs. Electricity costs are low – our most popular unit OMF500 runs at 500w.

  • My machine is a @@@@@@ which machine do you recommend?

    Contact us with details of your machine and the coolant in use and we will confirm our recommendations. A site visit would then be required to confirm suitability and discuss duct layouts.

  • Who are you?

    “We are part of AirBench Ltd, one of the UK’s leading fume and dust extraction equipment manufacturers.

    In mid-2014, Air Cleaning Systems Ltd, the manufacturers of the OMF range, went into liquidation. AirBench Ltd acquired this (successful) range from the liquidators, and alongside selected team members from ACS have reintroduced the product to the market.”

  • Why should I buy my mist filtration system from you?

    The OMF range have been proven in service and in recent years have been one of the leading brands of mist filtration units in the UK. We can introduce you to satisfied customers across the UK and Europe.

  • Why should I buy an OMF rather than a cyclonic filter?

    Cyclonic filtration is effective down to 10 microns. Below this level, efficiency drastically reduces. Coolant mist can be sub-micronic – the final stage HEPA fllter in an OMF allows for very high grade filtration.

    In addition, cyclonic filters may require daily maintenance – compared to monthly maintenance for an OMF. This is a significant time commitment.

  • How often do I clean the filters and how do I know when to do it?

    “The pressure gauges on the front of the unit show when the filters are full. The primary filter can be cleaned; in general, filters will require cleaning every 1-3 months depending on level of use.

    The HEPA filter cannot be cleaned, and must be replaced when full.”

  • How much are replacement filters

    Contact us for current pricing.

  • Can the ducting be removed easily so I can move the OMF

    “Yes. The ducting is clipped together; disassembly and reassembly is usually a quick process.

    Contact us prior to moving to ensure you have sufficient ducting, and check the fan is capable of handling any pressure difference.”

  • How often should it be serviced?

    “Annual servicing is more than sufficient; in most cases these units run for many years with minimal attention and only a basic check by an engineer is required to keep the system operational (plus filter changes as required).

    Note however that as an LEV system all extraction units should be tested every 14 months to confirm they are working as designed.”

  • Do you offer a servicing contract?

    If you would prefer a service contract, contact us to request pricing.

  • Is PPE required when changing filters?

    Yes. You should wear PPE when working with coolant.

  • How long will the installation take?

    Installation is normally completed by customers. It is designed to be a quick and simple process, even for larger booths; although there is some heavy lifting; if in doubt, contact us, and we can provide support.

  • What wiring options are there?

    Typically, each VertEx is a single phase unit with a 13a socket. We can configure with multiple wiring options; units can be daisy chained or linked to a distribution board; built for 3 phase; or controlled remotely. We use intelligent fans which allow many control options.

  • Does it need a single or three phase supply? What voltage?

    Usually, 230v 1phase. 415v 3phase versions are available, generally at no additional cost.

  • Do you install?

    If you would like us to, and at a small charge. However, our modular units are designed for self-installation.

  • Can you connect ducting to the outlet?

    If required; we will usually advise on our initial assessment visit.

  • How many VertEx units can be installed together?

    As many as you want. Our moular booth system allows for changes in production areas or unit configurations, quickly and simply.

  • What is your delivery time

    Usually 4-5 weeks although if you are in a rush – ask us.

  • What colour are they?

    BS00A05 grey as standard. We can supply in other colours if required; just ask.

  • How long will the filters last?

    Typically 6-12 months, but this depends on the application.

  • What does it do /how does it work

    It draws dusts through the front of the unit, filters them, and returns cleaned air to the room.

  • What are the ongoing costs

    Running costs are low. Electricity consumption is fairly low as these are very efficient units; we publish power consumption data in our datasheets. The main component of running cost is filter replacement; filter costs depend on the unit type and filter spec so can vary quite widely. Contact us for details.

  • Can I have one in 110v?

    We can manufacture these units in 110v if required, although as a non-mobile item this is unusual.

  • Who are you?

    AirBench Ltd are the UK’s leading manufacturer of downdraught benches; VertEx products developed from the AirBench range and use many of the same design approaches and technologies.

  • How often do I clean the filters and how do I know when to do it?

    Initially, look at the filters after a week. This will help you determine the filter cleaning cycle. After this – typically this is a weekly or monthly task.

  • How often should it be serviced?

    These units are generally user-servicable for routine maintenance. We recommend an annual service when undertaking your LEV test – LEV testing is mandatory for all extraction systems and should be undertaken at least every 14 months (more often for some processes).

  • Do you offer a servicing contract?

    We are happy to offer service contracts for annual testing and maintenance.

  • Who are you?

    “We are part of AirBench Ltd, one of the UK’s leading fume and dust extraction equipment manufacturers.
