Washable Framed Panel Prefilter allows coarse-filter maintenance while retaining the rigid aluminum frame. The supported removable media can be cleaned or renewed separately, making it useful where prefilters are reached and serviced frequently.
FEATURES AND BENEFITS
How it helps
Coarse-dust interception
The G4 stage catches larger dust ahead of coils or finer filters, placing regular cleaning at an accessible first stage.
APPLICATIONS
Where it is used
Frequently serviced air intakes
Use in ventilation systems with a planned wash-and-refit routine.
Return-air maintenance
Provide a removable coarse-filter element where the rack can be reached without dismantling the duct.
SELECTION GUIDANCE
Choosing the configuration
Return to service
Allow cleaned media to dry and refit it securely; replace damaged media rather than relying on the frame alone.
