TREATED FRESH AIR UNITS ( TFA )
Treated Fresh Air Units (TFA) Supplier in India – High-Quality Fresh Air & Ventilation Solutions | Compress India
TFA stands for Treated Fresh Air. A TFA unit is an air handling unit that takes 100% outdoor air and cools, dehumidifies and filters it before it reaches the occupied or process space — as opposed to a normal AHU, which mostly recirculates room air. On drawings and equipment schedules it is also written as TFA unit, TFU or, where the unit feeds terminal equipment rather than the space directly, PAU (Primary Air Handling Unit).
The reason TFA exists as a separate machine is load separation. In Indian conditions the latent load in outdoor air is large and varies independently of the sensible load in the space. Handling it in a dedicated unit lets the TFA hold supply dew point while the FCUs, VRF indoor units or cassettes downstream deal only with room sensible load.
We do not manufacture TFAs — we only supply genuine, high-efficiency units sourced from trusted and authorized HVAC brands.
What Are Treated Fresh Air Units (TFA)?
Understanding Treated Fresh Air Unit Systems
A Treated Fresh Air Unit (TFA) is an HVAC system that filters, cools, heats, and conditions outdoor air before delivering it indoors. TFAs ensure high-quality ventilation by providing clean, temperature-controlled fresh air to buildings. The term treated fresh air units TFA is commonly used in HVAC designs for malls, office towers, hotels, hospitals, and industrial environments.
