Hey guys what do you know about pelco's pressurized housings? how well do they work? And are they good enough to back with a warranty?

no one?

guess there has to be a specific reason to go pressurized...........and most of us don't have any customer willing to pay for "pressurized" when it really buys you nothing. unpressurized work fine in "normal" installs.

oh no this is by no means a normal install. This is a quarry where they crush rocks and is very very dusty. The existing housings that were set up perfect get full of dust DAILY. So pressurized housings look like a good idea to me.

panasonic makes pressurized housings good for dusty environments like that. check those out.

If you use a weatherproof houring with a rating of IP 65 or better, then it should be impossible for dust to gain access.

 

It is likely that there would be some minimal air movement with variations in temperature, particularly past the cable gland sleeves, but this would not result in large amounts of dust being drawn inside the housing. A pressurised housing would be something of a luxury, particularly where conventional housing designs should in theory be more than adequate for the job.

Ive used the Kalatel (GE) housings for a few years, never got any dust in them, very dusty environment, and on the beach, same location had a $20 housing from the previous job, is full of dust. .
