My air compressor turns off at 175 psi, but the RapidAir home garage kit has a maximum pressure of 150 psi.

All air systems should be fed at the start of the system with a regulator unit. The regulator is typically set between 90 to 110 psi. The regulator maintains constant pressure for your air tools regardless of what the compressor turn on and shut off limits are. The regulator will keep the system pressure below the rated maximum pressure of the kit. Most air tools are rated for a maximum of 120 psi, so it's best to keep your system pressure below that limit.
Water vapor is created when the compressed air temperature is high. Water vapor is the hardest to filter and separate out of the air stream. Cooler air turns the water to liquid, which makes it easy to filter. The further the filter is placed from the compressor, the cooler the air will be.
The most practical place for the filter regulator is close to the air compressor. This makes it convenient for mounting and plumbing the air system. To perform properly, It's best to be at least 20 ft from the compressor. But some garages are not even 20 ft wide. While it might not perform at 100%, putting the unit next to the compressor will still work adequately.
Yes, our products are OSHA rated.
OSHA does not approve any products for safety but does rely on the manufacturer for recommendations. Since we manufacture our piping for compressed air and have verified its performance, it is allowed.
OSHA has issued guidelines that PVC plastic pipe cannot be used for compressed air piping.
There is no difference in materials for the different colors of tubing or piping that we offer. The reason for the different colors is so maintenance workers can know which gas is flowing inside the pipe.
Blue is used for Compressed air and Green is for inert gases.
The RapidAir Home Garage kit uses push-to-connect style fittings, which designate their measurement on the outside of the tubing. The RapidAir tubing measures 1/2' outside diameter x 3/8' inside diameter.
The MaxLine system uses compression fittings, which designate their measurement to the inside of the tubing. The MaxLine 1/2' tubing measures 5/8' outside diameter x ½' inside diameter. For longer piping lengths, the MaxLine would offer more flow rate (CFM).
There are a few ways you can remove moisture from your air system. You'll find that the more you spend on the dryer unit, the better it will perform.
For example, a simple $80 moisture trap/filter uses centrifugal force to remove the moisture and most water vapor will pass right thru the unit.
A $400 desiccant system works well, but uses a media similar to oil dry to catch the moisture. This media needs to be changed often. These units still allow some water vapor to pass through.
A refrigerated dryer operates like a de-humidifier and is electrically powered. It lowers the dew point of the air passing through it, which removes all the moisture and passes clean, dry air through it. A typical refrigerated dryer for a 5 hp compressor would cost $.

How do you know when it's time to retire your old iron distribution piping? Black iron piping is still commonly used for compressed air distribution, but this type of piping doesn't last forever ' and an aging distribution system could be costing you more than you realize. If you're wondering about the RIO of upgrading to aluminum piping, read on.
The service life of your compressed air distribution system depends largely on two factors: the material chosen for the piping system and how well you take care of it. A black iron piping system can last 20 years or longer with proper care or may fail in as few as ten years. A big part of that difference comes down to moisture levels in compressed air.
Iron pipe is prone to corrosion when exposed to moisture ' and compressed air, you may remember, can be full of moisture. When iron rusts, you will see corrosion buildup, called scale, on the inside of the pipes. Over time, buildup of scale will narrow the inside diameter of the pipe, constricting airflow. Flakes of rust can also break off inside the pipes and clog inline filters or contaminate the air supply.
You can extend the life of your black iron piping by keeping air as dry as possible through the use of air dryers and filters. However, even with good care, it is virtually impossible to avoid all moisture and the resulting corrosion. Eventually, the pipe will deteriorate to the point where it must be replaced.
All things being equal, aluminum piping has a longer service life than black iron. Aluminum piping can last for several decades with proper care. What makes the difference? Unlike iron, aluminum does not rust. When exposed to oxygen, aluminum forms a layer of aluminum oxide which is protective against further corrosion. That means that aluminum distribution piping won't develop the scale problems common with black iron. Under similar working and environmental conditions, you can expect aluminum piping to outlast black iron by years or decades.
How do you know when to replace your black iron distribution piping? As the piping degrades, you'll notice several problems, including leaks, excessive pressure drop, blocked filters and contaminated air.
An aging compressed air distribution system will add to your operating costs in several ways. Some of these costs may include:
When the time comes to replace your distribution system, it pays to invest in a higher-quality, longer-lasting piping system. Aluminum piping costs a bit more than black iron up front, but it will pay for itself over time. It takes about five to seven years to recoup the cost difference between aluminum and iron through lower operating costs. When you factor in the longer service life ' in most cases, much longer ' the return on investment (ROI) for aluminum distribution piping is quite high compared to other piping materials.
Aluminum pays for itself in several ways.
When you are installing a new compressed air distribution system, or replacing an old one, it is important to look not only at material costs but also installation costs. A modular aluminum piping system like Unipipe is much faster to install and does not require special tools. That leads to savings on two fronts: labor and downtime. These savings may make up a large part of the cost difference between aluminum and iron.
Replacing your compressed air distribution system is a major investment in both money and time (which is also money). If you currently have an aging black iron piping system, it makes sense to get as much service life as you can from it. But if you are experiencing excessive problems with your compressed air distribution ' leaks that develop faster than you can patch them, dirty air, excessive pressure drop, or a compressor that can no longer keep up with air loss and pressure drop ' it may be time to think about an upgrade. When that time comes, aluminum may be the smartest choice.
Unipipe is the best compressed air piping system on the market. Its high-quality aluminum construction and innovative fitting design result in years of leak-free service. That's why Unipipe backs up their systems with a 20-year warranty ' the best in the industry. Unipipe is fast and easy to install and is manufactured to the highest standards. In addition to compressed air piping, Unipipe is available for nitrogen, vacuum, high-pressure and multi-fluid applications.
