P1000 Positive pressure cab

[Markeabe]

Has anyone ever tried to apply a positive pressure fan system for an enclosed cab on the pk1000. I am considering installing a panel of hdpe material between the rop's and Honda factory roof with 2 small radiator fans that would draw their air from the rear area behind the mid panel, through filter media. My thoughts are that this would provide a positive pressure to the cab to keep the dust down and also provide cooling for the front passengers. This type system works for construction equipment cabs.

Fans would be loud but I like the concept, I have 3 radiator fans (2 I was going to use under the seat to move hot air) that I use for workshop air filtration and they are LOUD. Move a lot of air and filter a lot of dust from the air when I am sanding. I would try 1 fan and a couple feet of flex duct that MIGHT reduce the noise from the fan. try to run a pre-filter AND a post filter the post filter would keep the fine particles and cut some of the noise down and the pre-filter would protect the fan and keep the post filter from closing as quickly.

So.. I have a prefilter I use on my snorkel for the air box...

Why not just T off of it under the hood and run a duct under the dash somewhere with a small bilge fan in line. Or if you don’t want to snorkel you could just have the filter on the end of the duct under the hood.

Didn't someone try this with roof fans but I don't remember a filter being used.

Yes the fans would have to be controlled with a variable speed controller to reduce speed and reduce the noise and air flow to the cab.

From my experiences with hot rods good electric fans can draw a lot of amps. It seems that it would be easy to overload the factory charging system.

Noted on the current draw, I would use a variable speed controller to slow the fan considerably from their full voltage speed, they will draw way less amperage when on lower speed, and be considerably less noisy. The speed controller would be a PWM type (pulse width modulator) which adds very little current draw to the circuit but allows to reduce speed considerably without harming the motor. Lower speed equals lower amperage on this type circuit.
I will be doing a mockup later this spring to test before any permanent install.

I also have all my accessories connected to my auxiliary battery, as, in my opinion, should all pioneer owners due to shifting issues associated with under voltage at the clutch.
