About Industrial Air Receiver Vessel

Air Reservoir Complete Information

 What is an AirReservoir?

An air reservoir, also known as an airreceiver tank, is a pressure vessel used to store compressed air before itenters the piping system or air-consuming devices. It helps in maintaining consistentair pressure, reduces compressor cycling, and acts as a buffer during peakdemand.

 Function andBenefits

Stores compressed air for future use
Reduces pressure fluctuations
Dampens pulsations from reciprocating compressors
Acts as a heat exchanger (air cools down before use)
Helps remove moisture and oil droplets
Reduces compressor wear by minimizing load/unload cycles

 Types of AirReservoirs

Vertical Air Reservoir Saves floorspace, commonly used indoors.
Horizontal Air Reservoir Easier access for maintenance, used where heightis restricted.
Mobile/Portable Reservoir Mounted on wheels for mobile applications.
