Treated Fresh Air Units Products > Treated Fresh Air Units

We are involved in the manufacture, export and supply of Treated Fresh Air Units which provide a complete solution for cooling, heating, humidification, high efficiency filtration, mixing, sound attenuation, etc. This treated fresh air unit works best for saving energy in a single modular unit with option to add modules.

FlexAir Energy Recovery Ventilator (ERV)... FreshAir solution from the Airgineers

FlexAir Energy Recovery Ventilator are equipped with EcoFresh Heat Recovery Wheels; capable of recovering more than upto 75% of each sensible and latent energy from the stale exhaust air and transferring it to the fresh outside air. The rotating wheel transfers the sensible and latent energy between the counter flowing exhaust and supply air and in the process preconditions (cool/heat/dehumidify/humidify) the fresh air.

An FlexAir ERV helps to meet Ashrea 62 specified ventilation rates without increasing the air conditioning tonnage, saving capital and operating costs considerably.

Available in five models, FlexAir ERVs address the basic requirements of a commercial energy recovery ventilator including--

High energy transfer efficiency (both sensible and latent) (Making it the ideal choice in tropical regions as India)

No cross contamination - Cross contamination between air streams limited to an absolute minimum with molecular sieve 3Å* (Ecosorb 300) coated energy recovery Wheels.

Economical first cost

Low operating costs

Low maintenance


FlexAir ERVs are the preferred option in S.E. Asia, West Asia, Middle East and Far East, Africa, Indian Subcontinent, CIS Countries, New Zealand and Australia.


The Ecofresh rotor is the first choice of OEMs in N.America, Japan and Europe.


New Modular Design . . . More Model Options:

The new design allows for several functions to be placed in the same casing. The FlexAir series has a wider range to cover the flow range better making it possible for you to easily select the right unit with the lowest LCC.


Advantages with EcoFresh Inside

ARI Certified (270mm deep-MS Series).

Modecular sieve coated.

Almost no cross contamination.

Over 80% energy recovery both latent and sensible. Ideal for tropical climates where latent loads are 2-3 times the sensbile load.

Total energy recovery, recovers both latent and sensible energy.

Specially, adjustable purge section rules out cross contamination of air stream (less than 0.04%).

Most advanced technology.

Special sealing arrangement ensure no cross leakage of air stream between the supply and exhaust section.

Certified / Tested in international labs.

Wheels' edges hardened to suit marine / coastal application needs.

Best LCC (Life Cycle Cost).


Flexair Treated Fresh Air Units

Flexair Treated Fresh Air Units provide a complete solution for IAQ and Energy Saving in a single unit. Modular with option to add modules for cooling, heating, humidification, high efficiency filtration, mixing, sound attenuation, etc.
