Not all air intakes are the same (part 2)

Some do not have the additional protection provided by 

 

 Permatron Air Intake Filter Screens.

During part one of this blog we referenced some key considerations based upon the RAB experience of this sector. 

A lot of people have taken an interest and have been kind enough to write in with their own stories of clogged coils etc. 

Response 1

While working for a consultancy I was called on to inspect a plant where there had been a failure of a Carrier 5H86 compressor in a shopping centre that the office looked after and I found the filters and evap coil  looking like they had been lined with cardboard. As you can imagine the compressor had liquid refrigerant enter it, wash out the oil and destroy the valves.  

Response 2

I was asked to view a job near to the Shard today. There is a problem with construction dust which is being sucked into the intake louvres on two McQuay AHU's. This dust is everywhere and is clogging the filters which is reducing the air supply to the building. Is this something that your screen filters will cope with?

Response 3 

On walking around the outside of the place I came to a plantroom that contained the equipment servicing a day treatment area. The grille for the air handling unit was so matted over it looked like it had a blanket across it. 

 

Summary

It is very easy to ignore the facts which are:

• Coils and air intakes DO become clogged with airborne debris.
• Running equipment with a dirty coil DOES cost more.
• Cleaning a PreVent air intake filter screen IS very simple to do.
• Cleaning a matted coil IS NOT very easy to do.

 

 

 

Not all air intakes are the same.

A simple and innovative solution to improve plant maintenance.
