Getting moisture inside the gun can wreck it... does this pump have a desiccant tube or silica gel or anything to scrub water out?

Yes there is a desiccant attachment... go tohttp://www.opticsplanet.com/sun-optics-desiccant-kit-for-high-pressure-hand-pump.htmlI have one and it seems to work well.... also they sell rebuild seal kits to rebuild when needed...

When I returned the pump the second time they added a desiccant tube at no charge - the pump still failed me. I have a $179 boat anchor.

When 80% humidity air is compressed from 13.7 psi (sea level) to 4000 psi, the partial pressure of the of the water vapor becomes so insignificant, the air is essentially dry. Go to a scuba shop for any further clarification or buy a chemistry book and look under partial pressures. That is why regular compressed air from a scuba tank becomes oxygen toxic to a diver below 250 feet to scuba divers. They suffer oxygen narcosis at that depth. Therefore no desiccant is needed for 4000 psi pumps. The desiccant attachment was added so they could charge extra for people who demand one instead of teaching them chemistry and explaining why one isn't needed.

I have not yet had to replace mine, but if/when that time comes I would think that some of heat gun elements offered on ebay, compatible w/ Liester or Bak Rion heating guns would work as a replacement. I second the recommendation to let the heat gun run on level zero to allow the element to cool after use. I just let it run until the gun nozzle is cool to the touch.

Most of the gun you are asking about is mostly plastic (main body, handle, etc) The only metal parts are the nozzle tube, the aluminum block it connects to inside the main body, the can connector, and the control rod inside the dispenser tube. Good maintenance should let this gun last quite a while.....I had one work flawlessly for 3 years......sparing use of cleaner and only clean tip with fingernail or credit card - type material is suggested

The. Pump dont make the water clear the chamical clean it. The pump just clean it

take the pump out and remove the tube..look carefully inside (use a flashlight) gunk get built up along the sides of the tube (hard to see). If that is clear open up the pump it has 2 areas where u can put in a very small screwdriver to get it open. I have found tons of gunk in there. Good luck. I ended up not using mine anymore, much easier just to fill a bowl with clean water every day.

Your gonna have to use pipe pliers to get it off. Be sure to clean the gun thoroughly before using it. For whatever reason these monkeys put some sort of glue on the threads of everything and it sucks. Use lacquer thinner it's the only thing that worked for me I soaked the gun and ask the parts in it for a few hours and scribes the crap out of it. Works pretty good once cleaned properly

Yes I had the same fault when I started the engin. My shockes had cracks in the rubber air bag and allowed moisture to get in to the pump. Causing the air dryer to fill up with moisture and eventually ruin the pump.

You might have a piece of gravel or a small snail stuck inside. I would take it apart and use a cotton swab to see if anything comes out. It's one of the quietest pumps on the market.

Every portable that I have owned has a drip tray with it. If not measure the distance between the dehumidifier and the drain and buy one foot of tubing more. This pump is for my heater and has a lot of condensate

This device IS NOT for removing the refrigerants. This pump is used after the system has been opened and serviced. It's purpose is to draw out the air and moisture prior to recharging; which are discharged into the open air.

Hook the tubing to the bottom of the gun. For the gun there is a drawing and description under the foam of the case. Still flummoxed? You tube has airbrush assembly videos.

We got distilled water, wiped it down with the distilled water, not a soaked wipe down, a lite wipe down. Then fill the shot glass with distilled water, sit for 24 hours without opening it. Then another wipe down with the distilled water just like the first time, then wet the humidifier that comes with it and load your items. i have to refill the humidifier every other day because I live in Tucson and everything drys out here.

The amount of water it absorbs depends on the relative humidity surrounding it and also how long you leave it exposed. The "equilibrium moisture content" of silica gel at 90% humidity is about 35% by weight, and this product has 750 grams of silica gel, so about 260 grams of water at that relative humidity. However, at 50% relative humidity, this "EMC factor" is only about 25% and therefore can only hold about 180 grams of moisture. I have tested these indoors and outdoors in Oregon (50% and 90% relative humidities, more or less) and these numbers are roughly right. It took about 2 weeks for it to fully saturate in 90% relative humidity and probably twice that in 50% relative humidity. The rate of water adsorption slows down as it gets close to saturation. Note that at 100% relative humidity the amount of water vapor in a volume of 1000 cubic feet depends almost entirely on the temperature and is about 13 ounces at 50 degree Fahrenheit and 47 ounces at 90 degrees Fahrenheit. At 50% relative humidity, the water content would be half of that. It is probably better to look at devices like this as "moisture buffers" instead of "moisture adsorbers." If the silica gel is saturated at 90% relative humidity and you put it in a drier environment, say 50% relative humidity, it will actually release some of the trapped moisture until it reaches equilibrium again. Probably more than you wanted to know about this, but I have been studying it to see if I can find a solution for my boat while it is in storage, and I'd like to find something that doesn't need "recharging" every 2-6 weeks. By the way, it is NOT effective to "recharge" these in a gas oven because the combustion releases water vapor, making it difficult to ever get the silica gel really dry. I ended up buying an electric toaster oven to solve this problem. (Makes better toast, too!)

Hi Jordan, Everytime I use mine I run warm water through it till it runs clean misted water. Everytime. It's the only way I've found to maintain the gun and I've had this system for 2 years without issue

It's basically silica gel. Cobalt chloride is added as an indicator of the absorbed moisture. I did not specify an indicator with my order of packets, but I did order two desiccant dryers with indicators that I can judge the moisture content against the smaller packets. Easy enough to "recharge" them by drying in n oven at 250f for an hour or so.

won't hurt, but most pumps come prelubed. just don't run it without water ever and oil.
