Restricted air flow is a major problem for equipment. It causes longer cycle times at reduced capacity, higher energy consumption, higher temperatures, costly repairs and downtime, and shortened equipment life. 

Causes to these problems include seeds, leaves, insects, and industrial processing and construction debris. 

Equipment operation with dirty coils can use as much as 37% more energy than equipment with clean coils, therefore, costing more money to run a clogged unit. Cleaning these units can be costly by leading to system downtime, messy chemical cleaning, environmental drainage issues, and labour intensive hand brushing.

Industry experts agree that preventative maintenance can double the useful life of equipment and reduce HVAC energy bills by more than 20%! 

Permatron's PreVent equipment protection filters are a proactive solution to preventative maintenance.

PreVent filters are:

• Cost effective
• Custom fit
• Easy to install
• Easy to clean
• UV protected

PreVent equipment protection filters are low maintenance and durable so they can be cleaned in place, which means no system downtime. As needed, simply brush debris off with a broom, stiff brush or shop vac. PreVent has custom installation options made to work with any type of equipment air intake!

Ways you can save with PreVent® :

• Cut maintenance time - complete more jobs per day
• Stop unnecessary breakdowns
• Longer capital equipment life
• Decrease energy use
• Extended interior filter life
• Customer satisfaction

What does an air intake screen do?

Keep it simple stupid

A customer said recently that the best engineering solution is quite often the simplest.

We have all heard of the KISS acronym (Keep It Simple Stupid) first introduced by the US Navy in 1960 as a design principle.

The KISS principle states that most systems work best if they are kept simple rather than made complicated (http://en.wikipedia.org/wiki/KISS_principle).

So when a client needed a solution to prevent airborne debris getting into the air handling units and cooling coils, RAB did exactly that.

The first problem was an air intake to a VES AHU which was sucking in a large amount of contaminant which shortened the life of the filters considerably.

Steel frame, BHC media and a magnetic strip riveted to the frames solved that problem as you can see from the picture taken only 10 minutes later and the second picture after 2 weeks.

That left the Mitsubishi City Units sited all around the building.

Keeping it simple we used a wrap around air intake screen placed over the coil air intake faces and secured using Permatron Bungee Cords.

And what about installation? Start and finish in less than 30 minutes.

AIr intake screens - so easy to measure

How to measure your opening for an air intake screen?

It is not a difficult task. Anyone with a tape measure and a pencil can provide sufficient details for an air intake screen to be quoted within 24 hours. .

There are no complex templates because the basic principle is always the same.

You have an air intake opening that you want to fit an air intake screen to. It might be square, rectangular, trapezoidal or any other shape that you can think of.

For this example we will measure a trapezoidal opening. It looks complicated but with a manufacturing base that says "If you can draw it we can make it" the dimensions are simple to take:

Measure the following
A to B
A to D
B to C
D to C.
Finally measure the distance between line AB and line DC

This will give you the internal dimensions of the opening which should have a framework around it. Measure the width of the framework and you have all of the dimensions you need.





A quick hand drawn sketch of the shape and a picture finish off the survey. 

If you have a vee coil, take a picture and then measure the external dimension of the framework plus the internal dimension of the coil itself. This will give us sufficient information to submit a quotation for your new air intake screen.

The picture below shows a Kanya Framed air intake screen mounted on galvanised folded steel runners. 

Louvres, cooling towers, condensers, dry air coolers etc. can be easily quoted with some outline dimensions and, once you like the price, one of the team will attend site to double check the  measurements before we manufacture your new air intake screen.
