Met – Pocket Filter

The Met Pocket filter series is an excellent choice for secondary & fine filter requirement, it is generally used in

Automotive paint booths, Health Care facilities,
Commercial buildings and other industrial filtration requirements. Available in both synthetic and glass fibre media, these filters can be designed with varying number of pockets to suit different air flow requirements.

Pocket filters lend flexibility for upgrading of the air quality to meet the needs of the manufacturer. These are also cost effective and highly efficient since there is very little metal support and what is discarded is mostly the choked media which in any case needs to be discarded.

You could choose from the following options:
Media: Synthetic (High loft, standard loft with/without aerodynamic spacers) Glass fibre media
Frame: Galvanised iron, aluminium, plastic & powder coated MS
Edge Sealing: Ultrasonically welded, stitched
Construction: Box /Flange

OT PLENUM

Laminar Air Flow plenum is used to create a sterile working area free of bacterial contamination generally located above the operation table & is made of Aluminium/ SS-304 Sheet for suitable strength. In case of Aluminium after the completion of initial fabrication, the plenum is cleaned & powder Coated to give additional protection & Aesthetic look. The Laminar Air Flow is designed in such a way so as to cover the entire operation table, sterile surgical equipment’s & doctors. Each Plenum is equipped with provision of fixing of HEPA Filters, DOP port (Required for HEPA filter integrity test) & built in dampers for controlling the air flow across the HEPA Filters. Provision for fixing the lights is also given if required. Double Skinned plenum is also available.

Met Air Fan Filter Unit

FFU (Fan Filter Units) are used in cleanroom facilities to reduce the concentration of particles.

FFUs are typically installed in a grid pattern on the ceiling of a cleanroom to provide a continuous flow of clean and filtered air from above. This downward laminar airflow helps maintain a controlled and clean environment by preventing airborne particles from settling on surfaces or contaminating sensitive processes or products.
