Outstanding Developments

A new pioneering concept in air filter design for four wheelers has been initiated. The revolutionary hi-tech eco-friendly next gen filters have been introduced with a major automobile manufacturer in the country.

MNR has successfully developed superfine filters for ISRO resulting in 33% reduction in current drawn by the blower to save enormous energy.

MNR has been retained by a multinational compressor company for the design, manufacture and supply of test facilities, apart from providing filters. The fully automatic test rigs are used for testing different HEPA filter cartridges and are equipped with D.O.P generators, digital photometers etc. The cartridges vary from less than 100mm to one meter in height and aerosol application is done by linear motor drive for uniform travel. The test rig size is 2500mm long by 750mm wide and a height of 2500mm. All operations by the operator are ergonomically planned.

A standard Pocket Filter experiences a high and turbulent face velocity. Our design enables the turbulent flow to be converted to a uniform laminar flow at the outlet. This results in uniform loading of the pockets and ensures longer life.

Our in-house test facilities rank as one of the foremost in the country. We are on the approved list of Defence, D.G.S.D, ISRO, C-DOT, N.P.C, N.T.P.C, N.S.I.C, Rail-Wheel Factory, and other organizations.
