Answer: 
You need the Gun, Grainger Item # 1GDL7 and the Cartridges, Grainger Item # 1GDL8. Good product, I'm using it for 5 years, you only buy the guy one time, then just the cartridges, they have CO2 with high pressure to blow the clog away, if the pan is dry put little bit water first, that help to push the clog. it came with a short hose and adaptors.

Pressure Problem

What happens if a fan rated for 4 to 9 inches of pressure (water gauge) is run at maximum allowed speed at 0 inches of pressure? Will that be "over-speeding" the wheel and cause structural failure?

Answers

Answer: 
If you do not pass the maximum speed (RPM) the wheel should be ok, no matter the pressure, but the maximum speed is very high, usually higher that the operational speed (RPM) that the fan actually work, on this case the fan will be very close where it will vibrate very easy and them will break, so don't get at the maximum speed. You "over speeding" the fan if you pass the maximum speed and it will break. Also note that because you when to a higher speed you need more power HP to operate the fan.----- higher RPM: higher CFM: higher HP

The HOA I am in hired a bunch of misfits who do not know how to weed whip without bending the fins on the bottom of my home unit. I am looking for a comb to run down from top to bottom to straighten them out again. Obviously, they denied doing anything to it. Of course. The unit works perfectly because I just paid to have it serviced for the summer, but the Tech did not have the tool with him to straighten the fins when he came.

Answers

Answer: 
PS4028,
Look on your coil what size comb you want, so see how many fits you have in one inch. Select the item Grainger # 2YJ77 OR 2YJ76 .The packet came with six different combs, but be sure you buy the one will work for you. If your service technician does not have one, them hire other technician, this is a tool that we carry on the truck. The unit should be sit on a base, (four concrete blocks will work) not on the floor, do not weed around your unit, you will damage the coil, spray weed killer around the unit, kill the weed six inches around the unit. Also watch the refrigeration pipes, if they hit the cooper pipes or the insulation, if it's working fine then are good.
