Drain Type Guide
The drain at the bottom of a filter bowl removes collected condensate. Choose a drain arrangement that matches access, maintenance frequency, and the behavior described for the individual model.
Common drain categories
Manual drain
The user operates the drain as needed. It is simple and gives direct control, but depends on regular inspection and service.
Semi-automatic drain
Operation can depend on system pressure and the specific mechanism. Review the product instructions instead of assuming all semi-automatic drains behave the same way.
Automatic drain
Designed to reduce routine manual draining, with operating conditions and behavior that vary by model.
Application check
Consider condensate volume, access below the bowl, service routine, and whether discharge needs to be directed safely.
Before selecting
- Read the exact drain description on the product page.
- Confirm required pressure conditions for drain operation where applicable.
- Allow access and clearance for inspection and service.
- Plan for safe condensate discharge.
- Inspect the bowl and drain regularly according to system conditions.
