Air tank / compressed air pressure vessel

The role of the air tank in the compressed air system is storage of air under pressure, and creation of a reservoir suited (as far as pressure and amount are concerned) to the customer’s needs.  The air tank plays a central role in keeping the compressed air system at optimal efficiency.

It is very important to match the air tank to the compressed air system and plant requirements (machines) from both the volume and working pressure aspects, in order to achieve optimal results as far as efficiency and mode of work are concerned. Poor matching will lead to inefficient operation and could also lead to irregular work of plant systems.

We recommend that calculation and matching of the air tank be done by one of our technical staff, who understands the needs of the air system as well as plant requirements. Thus, operation of the tank may be kept at high efficiency and reliability over time. The air tank accumulates within it air under pressure; hence, improper installation and maintenance could lead to less than optimal performance, and possibly even danger.

There are several approaches and methods for connection of the compressed air tank: The compressor can be connected directly to the tank, and from the tank to the air dryer. A more highly recommended approach in some cases is, to divide the air tank in two (Illustration 1) where one part is connected after the air compressor (“wet tank”), and the other part is connected after the air dryer (“dry tank”). Under this approach, the air dryer performs its work better. In addition, we reduce the risk of the dryer becoming overloaded, and moisture entering the air line.

EL-AV Compressors compressed air tanks are manufactured in compliance with ISO 9001:2015 and comply with the requirements of the American Society of Mechanical Engineers (ASME), with emphasis on quality and durability over time.

Our standard air tanks come in volumes of 50 to 1,000 liters, and are suited to work under the tough conditions characteristic of the Israeli climate. Each air tank comes with standardization and approval of any international institute according to the customer’s request.


Air tanks made to customer’s specifications

In addition to the standard tanks, tanks may be custom-ordered, made from different materials such as stainless steel, steel, and galvanized steel, with different coatings, in different volumes, and for different working pressures.

Our air tanks:

  • Maximum pressure - 11/16 bar (atm)
  • All tanks come equipped with a pressure gauge and safety valve.
  • All tanks come with four outlets - a drain outlet, and outlets for connection of accessories such as a pressure gauge, sensors, and a safety valve.
  • The tanks come with / without legs, shock absorbers, various adapters, and more.
