FAQ question marks
Yes, If you have a process that creates airborne contaminants like dust, fumes, vapours or powders.

BenchVent products are designed for multiple sectors including:
– Beauty and cosmetics (including airbrush tanning)
– Medical and dental applications
– Educational institutions and laboratories
– Electronics manufacturing
– Hobby and model making
– Art and design studios

It’s the Law. You can be fined or shut down if you fail to protect your staff or clients. It also lowers long term exposure which reduces illness and improves productivity.
Extracting airborne contaminants from the air and exhausting them direct to atmosphere (Via Ducting) or through a series of filters to re-introduce clean air back into the room (Recirculating)

BenchVent products stand out through:
– Cost-effectiveness compared to similar products on the market
– Lifetime warranty on all air filtration and fume extraction product
– Compliance with COSHH and HSE health and safety standards
– UK design and assembly with over 40 years of industry experience
– Special discounts for NHS, education, and military customers

Selecting the appropriate BenchVent product depends on several factors:

1. Application type: Consider what substances you’re working with (airbrush paint, solvents, dust, etc.)
2. Space requirements: Measure your available workspace to ensure proper fit
3. Airflow needs: More intensive applications require higher airflow (measured in m³/h)
4. Filtration requirements: Different materials require specific filter combinations

We are a family run business with over 40 years experience in the industry. Our units built in-house and are simple to use, quick to install and quiet in operation.

1. Unpack carefully: Remove all packaging materials and check for any shipping damage
2. Placement: Position the unit on a stable, level surface with adequate clearance around all vents
3. Filter installation: Ensure all filters are correctly seated according to the arrows indicating airflow direction
4. Power connection: Connect to a properly grounded power outlet matching the voltage requirements
5. Ducting (if applicable): For ducted models, connect the flexible ducting to the outlet port and secure with the provided clamp
6. Testing: Turn on the unit and verify proper airflow before beginning work

Refer to your specific model’s user manual for detailed instructions.

We take great care in the design and manufacture of our high quality, robust and reliable equipment. We provide a lifetime guarantee for all BenchVent manufactured products for peace of mind.
If you can accommodate a ducted unit this will remove 100% of the contaminants direct to atmosphere, or our Recirculating units through the process of filtration, adsorption and dilution, the operator exposure to concentrations of potentially hazardous substances is vastly reduced.
Our Units are designed to extract through a MAXIMUM of 4 metres of ducting, anything above this will negatively affect air velocity (2m supplied as standard per duct)

BenchVent products operate on standard UK power (230V/50Hz), with power consumption varying by model:

  • Smaller units (e.g., BV200H): Approximately 40W
  • Medium units (e.g., BV100H): Approximately 80W
  • Larger/ducted units (e.g., BV100H-D, BV930H-C): Approximately 210W

All units are designed for safe operation when connected to properly grounded outlets and are supplied with the correct plug type for the specific country of use.

LEV tests should be carried out every 12-14 months to ensure the machine is in fully working order. It also ensures that you and your staff are being adequately protected using the unit.
We recommend changing your particulate filters every 2-3 months and your carbon, HEPA or EPA filters every 6 months. If the machine is constantly in use, then filters should be changed more frequently.Signs that filters need replacement include decreased airflow, odours passing through the unit, or visible saturation of the particulate filter.

Genuine BenchVent replacement filters can be obtained through:
– Direct purchase from BenchVent (call +44 (0) 1423 790 039 or email info@benchvent.com)
– Your authorized BenchVent distributor
– Online through your BenchVent account at www.benchvent.com

We recommend using only genuine BenchVent filters to maintain warranty coverage and ensure optimal performance. Special filter discounts are available for regular customers.

No. You must extract through an external wall into the atmosphere. Our flexi-ducts can be installed to a standard domestic vent. Alternatively you can add our ducting into your existing ductwork.

The paper test is a quick and simple method to check whether a Local Exhaust Ventilation (LEV) unit is functioning correctly by confirming the presence of airflow at the filter face.

How to Perform the Test :

Hold a standard A4 sheet of paper directly against the front of the filter face :

  • If the paper stays in place without falling, the unit is operating correctly.
  • If the paper falls away, it may indicate:
    • Reduced or no airflow
    • Blocked filters or ductwork
    • Fan malfunction
    • Incorrect filter installation

Why use this test? 

  • Quick and easy visual confirmation of airflow 
  • Helps identify obvious performance issues
  • Ideal for daily or pre-use checks 

Important Note

This is a basic functional check and does not replace formal LEV testing, which must be carried out at required intervals according to local safety regulations (e.g., COSHH in the UK).

Beyond filter replacement, recommended maintenance includes:

Monthly:
– Wipe down exterior surfaces with a damp cloth
– Check for any obstructions in air intake and exhaust areas
– Inspect power cord for damage

Quarterly:
– Clean fan blades if accessible (power off and disconnect first)
– Check and tighten any loose fasteners
– Verify proper operation of controls and switches

Annually:
– Full inspection of all components
– Airflow velocity check (recommended for professional/industrial applications)

Reduced airflow typically results from:

1. Clogged filters: The most common cause – check and replace filters if needed
2. Obstructed intake: Ensure the air intake area isn’t blocked by walls or objects
3. Ducting restrictions: For ducted models, check for kinks or blockages in ducting
4. Fan issues: Dust buildup on fan blades can reduce efficiency (clean with power disconnected)
5. Incorrect speed setting: For dual-speed models, verify you’re using the appropriate speed setting

If airflow remains inadequate after these checks, contact technical support.

If odours are passing through your unit:

1. Carbon filter saturation: The most likely cause – carbon filters need replacement
2. Incorrect unit for application: Your current model may not be rated for the specific substances you’re using
3. Airflow bypass: Check for gaps around filters or in the cabinet that might allow air to bypass filtration
4. Excessive fume generation: You may be producing more fumes than the unit can handle at once
5. External factors: Check for other sources of odours in the workspace

For persistent odour issues, contact technical support to discuss your specific application.
