Clean Air or Dust Proofing Pressurization Systems

This kind of application is also a variant of the ventilation system. here fresh filtered air is pumped into the airtight department and exhaust is employed under controlled conditions mainly to ensure that the department is under positive pressure.

Positive pressure means,only air can go out of the department and no outside air can get inot the department to avoid dust entry into the department.

Forced exhaust is kept always kept at a lower side ,say,60 to 70% and balance is made to get through a preweighted gravity louvre which will open only when the department had reached a certain positive pressure.

Such kind of systems find use in switch gear rooms,pharmaceutical industries and in electronic components factories.
