Water Traps
Shop Tanair compressed-air water filters and water traps for removing bulk condensate and airborne contamination before it reaches tools, valves and machinery.
Tanair Water Traps for Workshops & Compressed Air Systems
The current range contains four complete water-trap assemblies with 1/4", 3/8" and 1/2" BSP connections, including both manual-drain and automatic-drain options.
These units help remove collected liquid water and general contamination from the airline before compressed air reaches downstream equipment.
A water trap is useful for local moisture control, but it does not replace a correctly sized refrigerated or adsorption dryer where a controlled pressure dew point is required.

The range is arranged by connection size, followed by drain type: 1/4" manual, 3/8" manual, 1/2" manual and 1/2" automatic.

Compact manual-drain water trap with mounting bracket for lower-flow systems, small workshops and point-of-use protection.
F14624-C/MB · 3/8" BSP
Manual-drain industrial water trap with mounting bracket for workshop, service-bay and general pneumatic applications.
F13634-C/MB · 1/2" BSP
General-purpose manual-drain water filter for garages, workshops and pneumatic equipment.
F15634-A-C/MB · 1/2" BSP
Automatic-drain option for busier or less frequently attended systems where condensate builds up regularly.
What Does a Water Trap Remove?
Moisture forms naturally as compressed air cools. A water trap separates liquid droplets and solid contamination from the airflow so condensate can collect in the bowl and be discharged.
- Bulk liquid water and collected condensate
- Dirt, dust and airborne particles
- Contamination that can affect pneumatic tools and components
- Moisture that can contribute to corrosion in local airline equipment
Which Drain Type Should I Choose?
Manual Drain
A simple option where the filter is easy to inspect and condensate can be discharged routinely by the operator.
Automatic Drain
Useful where moisture collects frequently, the system runs for longer periods or regular manual draining would be inconvenient.
Do Not Select by BSP Size Alone
Connection
Confirm the existing pipe or equipment connection before ordering.
Airflow
The filter must pass the compressor airflow without creating excessive pressure drop.
Drain Type
Choose manual or automatic condensate discharge to suit operating hours and maintenance routine.
Installation Position
Locate the unit where moisture protection is useful and the bowl and drain remain accessible.
Does a Water Trap Replace an Air Dryer?
No. A water trap removes liquid water that has already condensed in the compressed-air line. A refrigerated or adsorption dryer is used where control of the compressed-air pressure dew point is required.
Water Trap Installation Checks
- Install in the airflow direction shown on the housing
- Keep the bowl upright so condensate can collect correctly
- Support pipework so the housing is not placed under strain
- Leave clearance for bowl removal and element servicing
- Drain manual units before the bowl becomes overfilled
- Check automatic drains for correct movement and discharge
- Fully isolate and depressurise the compressed-air system before maintenance

Water Trap FAQs
What does a compressed-air water trap remove?
It helps remove condensed water droplets, dirt and airborne contamination from the compressed-air stream.
What connection sizes are available?
The current range includes 1/4", 3/8" and 1/2" BSP water traps.
Should I choose manual or automatic drain?
Manual drains suit systems that are checked routinely. Automatic drains are useful where condensate builds up frequently or the system operates for longer periods without regular manual checks.
Can I choose a water trap by BSP size alone?
No. Check airflow, operating pressure, drain type and application as well as the connection size.
Does a water trap replace an air dryer?
No. A water trap removes bulk liquid water; it does not provide the controlled pressure dew point of a refrigerated or adsorption dryer.
Where should a water trap be installed?
It is commonly installed where liquid-water removal and local equipment protection are required, while still allowing easy access for draining and servicing.
Can Compressed Air Systems UK help with selection?
Yes. Call 0121 753 3330 with the compressor details, airflow, pressure and connection size.
