Next, the guard. Like the balance of the unit it is constructed of stainless steel. It also meets OSHA standards.
We could have saved a significant amount of money by constructing the guard of normal steel wire rod and then powder coating it like with we do with some standard industrial air circulators.
I know, saving money is good but there are times when in the end it might not save money at all. Contamination! You can make quite a satisfactory powder coated guard for washdown duty (and in fact we do for our panel fans which are mounted high above traffic areas). But sooner or later you are going to bump into the guard on your air circulators! We know, we have seen what they look like after a few years of service. The problem with powder coating is that when the wire flexes the coating may chip. Where will the chip go? We have no earthly idea particularly if the unit is operating. There is a reason that many / most grow operations have people wearing lab coats or bunny suits isn’t there? Perhaps it is because it is a happy operation where they like to think it is Halloween every day, but we doubt it. It is because of contamination and the same reason that the guards of the Stainless Steel Washdown Duty air circulator are made of solid stainless steel.
Hopefully you now know where the “devil” is hiding and why your grow operation should have Stainless Steel Washdown Duty Air Circulators.
And finally, at left is a photo of the pedestal base. Notice that unlike a standard air circulator, the Stainless Steel Washdown Duty Air Circulator uses a five spoke open design that is slightly elevated from floor level on pads. The reason it is designed like this is to assure that you don’t have material hiding below the base. If material isn’t there you don’t have a hidden area for bugs and mold to hide either! And like the balance of the unit, the base is constructed of electropolished stainless steel and minimizes cracks and crevices in which dirt can hide.
Stop using equipment that is not designed for cannabis grow operations. We build washdown duty equipment that is guaranteed for long life in dirty humid environments in horticulture.
