HVAC Air Filter Dealers in Kolkata

The Caracas of the plenum will be made of extruded aluminum sections in such a manner that the air is passed only through the filters only. Plenum unit for laminar flow diffuser will be made of thick aluminum sheet. The complete unit will have factory prepared fine sealing system. The plenum will be supplied at site duly sealed in factory made packing. The Laminar flow system will have anodized aluminum perforated diffuser grill. The laminar flow system will have such design that it provides cleanliness of class 1000.  

Testing and certification for this range of filters has been sadly lacking in our country. For many years,and right upto the present time, efficiencies for this range of filters are reported in terms of BS 2831,which is an obsolete standard.Current international norms call for reporting of filters to be tested and evaluated in terms of ASHRAE 52.2, which specifies the rating of filters in terms of MERV (Minimum Efficiency Reporting Value). For the first time, filters are rated in terms of their efficiencies at a particular particle size, rather than in terms of simple gravimetric retention or dust spot efficiency. Spectrum is a pioneer in the installation of a test rig for the testing of filters in accordance with ASHRAE 52.2, and possesses a state-of-the-art facility for testing, evaluation and reporting of prefilters and intermediate efficiency filters. Spectrum also supplies prefilters and intermediate efficiency filters for various industrial applications, with media from Filtrair b.v., Netherlands, which is UL certified and certified for efficiency. Domestically available media are not certified, and their actual performance is therefore indeterminate. The Company thereby ensures that its products invariably satisfy client requirements with regard to filtration efficiency and dust holding capacity.

A highly contaminated filter will cause less air flow through cabin heating and air conditioning system and result in Evaporator freeze up Mold and mildew build-up in the evaporator case Foul odors in the passenger compartment Poor heat or cold air from ducts
