The final stage for cleanrooms, pharmaceuticals and laboratories: it captures 99.95–99.995% of particles at the most penetrating particle size (MPPS).
Glass fibre media is very densely pleated and separated by hot-melt beads. The face is covered by a protective grille, and the test label is on the side.
In a HEPA filter, tightness is everything: the bond between media and frame, and the seal. If either one gives way, the filter loses its class.
Among the fine fibres, particles are captured by diffusion, interception and inertia. The outlet air meets cleanroom requirements.
HEPA filters are supplied only with a verified test certificate; after installation we check them for leaks.
Send the cleanroom class and filter sizes — we will propose the filter class, seal type and post-installation testing.
