Air Compressor regulators and filters 

Here we look at Air Compressor regulators and filters what they are used for and types.

Air regulators must be of sufficient air flow capacity for the largest demand at the output and will be rated accordingly and fitted only where a regulated supply is required at spraying points.
Filters (or separators) must also be of the correct air flow rating and are normally integral with the transformer. A filter with drain cock must be incorporated after the regulator and must not be allowed to become clogged with oil or filled with water which condenses from the air passing through it.
Frequent draining is essential in conjunction with periodic cleaning or renewal of the filter as appropriate.

• Failure to maintain filters will result in refinish defects.
• To be efficient, They must not be installed adjacent to the compressor, or near heating appliances.
• Each final output from the regulator/filter unit should be fitted with a shut-off valve prior to the female hose coupling.

Small-capacity moisture filters are available for fitting directly onto the spray gun inlet tail (between the air hose coupling and the gun) but
these must never be regarded as or used as a substitute for main airline filter units.
