Drains
Compressed air drains remove the condensate that collects in filters, dryers, receivers and drip legs. Removing water automatically protects equipment and keeps air quality up.
Drain Types
- Timer drains – simple, programmable discharge
- Zero air-loss drains – discharge water only, saving energy
- Float drains – mechanical, no power needed
- Internal filter bowl drains – automatic draining at filters
Choosing a Drain
Consider the condensate volume, pressure, power availability and oil content. Zero-loss drains pay back quickly by stopping wasted air. Route condensate to an oil-water separator before disposal.
Centro carries compressed air drains for filters, receivers and dryers.
