1. Overview & Purpose
The Camfil Megalam series represents industry-standard high-efficiency particulate air (HEPA) and ultra-low penetration air (ULPA) filtration. Built specifically for terminal hood installations, ceiling grid systems, and containment devices, these filters trap airborne micro-particles, bacteria, and dust to create ultra-clean environments required in sensitive manufacturing and healthcare processes.
2. Key Features & Construction
-
Robust Frame: Constructed from lightweight, extruded anodized aluminum with precision corner locks (Klip-Lok™) for structural integrity.
-
Protective Face Grille: Features expanded metal mesh screens on the face to protect the delicate media pack from physical damage during handling, maintenance, and installation.
-
Advanced Media Technology: Uses uniform mini-pleat fiberglass (or ePTFE membrane) media separated by hot-melt beads to maintain precise pleat spacing, ensuring low airflow resistance and uniform face velocity.
-
Leak-Proof Polyurethane Potting: The media pack is fully encapsulated on all four sides into the channel frame using fire-resistant polyurethane sealant.
-
Sealing Options: Available with either a fluid gel seal or a seamless continuous gasket to ensure a zero-leak connection with cleanroom housing units.
3. Efficiency Ratings
-
HEPA Grades: 99.97% to 99.995% efficiency at Most Penetrating Particle Size (MPPS) / 0.3 microns.
-
ULPA Grades: Up to 99.99995% efficiency at MPPS for ultra-high contamination control.
4. Primary Applications
