Filter Regulators
Tanair combined filter regulators for removing bulk moisture and particulate contamination while maintaining controlled downstream pressure for workshop and industrial pneumatic systems.
Combined Tanair Filter Regulators
This page is now focused on the true combined filter-regulator units. The regulator-only TAN-MAR products belong on the separate Air Regulators page and are not included in this product grid.
The live filter-regulator range covers 1/4", 3/8", 1/2" and 1" BSP connections, with both manual-drain and automatic-drain options. Selected FRC models use 50 micron filtration.
Choose by connection size, actual airflow, inlet pressure, required outlet pressure, drain type and filtration requirement — not thread size alone.

The range is arranged by connection size, with the 1/2" manual-drain unit shown before the 1/2" automatic-drain unit.

Need Regulator Only?
If filtration is already provided elsewhere, use the separate Tanair Air Regulators range instead of adding another filter stage unnecessarily.
What Does a Filter Regulator Do?
A combined filter regulator performs two jobs in one assembly. The filter section separates bulk moisture and particulate contamination, while the regulator section reduces and stabilises the downstream air pressure.
- Helps remove bulk water and particulate contamination
- Provides adjustable downstream pressure control
- Helps protect air tools, valves, cylinders and pneumatic machinery
- Reduces the number of separate components required at the point of use
How to Choose the Correct Filter Regulator
Connection Size
Confirm the BSP connection required by the pipework or equipment.
Airflow
The unit must pass the required airflow without excessive pressure drop during operation.
Pressure Range
Check both maximum inlet pressure and the outlet-pressure range needed by the downstream equipment.
Drain Type
Choose manual drainage for regularly attended systems or automatic drainage where condensate should be discharged without routine manual emptying.
Which Drain Type Should I Choose?
Manual Drain
Suitable where the bowl is easy to inspect and condensate can be emptied as part of routine operator checks.
Automatic Drain
Useful for busier or less frequently attended air points where condensate can otherwise accumulate between inspections.
Does a Filter Regulator Replace a Dryer?
No. A general-purpose filter regulator removes bulk moisture and particulate contamination, but it does not provide the controlled pressure dew point of a refrigerated or adsorption dryer.
Installation & Maintenance Guidance
- Install in the airflow direction marked on the body
- Keep the filter bowl upright so condensate can collect correctly
- Set outlet pressure while air is flowing where working pressure matters
- Drain manual bowls routinely and check automatic drains for correct operation
- Monitor pressure drop and replace the filter element at the appropriate service interval
- Fully isolate and depressurise the compressed-air system before maintenance

Filter Regulator FAQs
What does a filter regulator do?
It combines filtration and pressure regulation in one unit, helping remove bulk moisture and particles while reducing the downstream pressure to the required setting.
Why are the TAN-MAR regulators not shown here?
They are regulator-only products rather than combined filter regulators, so they belong in the separate Air Regulators range.
What connection sizes are available?
The current combined range covers 1/4", 3/8", 1/2" and 1" BSP connections.
Can I choose a filter regulator by thread size alone?
No. Also confirm airflow capacity, inlet pressure, required outlet pressure, drain type and filtration requirement.
What is the difference between manual and automatic drain models?
A manual drain is emptied during routine checks. An automatic drain discharges collected condensate without relying on manual bowl draining.
Does a filter regulator replace an air dryer?
No. It provides general filtration but does not provide the controlled pressure dew point of a refrigerated or adsorption dryer.
Can Compressed Air Systems UK help with selection?
Yes. Call 0121 753 3330 with the connection size, airflow and pressure requirements.
