Condensate Drains
Save on Compressed Air

Condensate Drains

Compressed air is expensive — every unnecessary blast from a timed drain adds up. Our zero-loss drain range eliminates that waste by only opening when condensate is actually present.

Timer-Controlled

Simple, reliable and low capital cost. The TD15 A/B solenoid drain suits applications where some air loss is acceptable.

Zero-Loss

Level-sensing drains (ZL310, ZL1300, ZL5000) only discharge when condensate is present — eliminating air waste and paying for themselves quickly.
