The right construction tools can determine the success or failure of a job. For roofing contractors, air compressors are one of the main ones.
“It’s very important for roofing experts to have the right roofing air compressors,” says Paul Vásquez, owner of PV Roofing in Houston. “I have many of them. We use them with staple guns and nail guns to ensure everything: from flashing to tiles. ”
The size of the team of workers and the type of work – remodeling, family residences, multifamily homes and even light commercial constructions – are also critical.
” Choosing the roofing air compressors that best suits your needs will depend on the size of the project and how many men you have working,” says Vásquez. “Air compressors also have to have a professional quality and be made to last.”
Air compressors come in a wide range of sizes, air supply ratings, horsepower, single-phase and two-phase. The most common type of compressor used by contractors generates air pressure with an alternative piston. Single-phase compressors have one or two pistons that compress and supply the air to the storage tank. Generally, one cylinder/piston pumps are found in moderate duty compressors with a maximum rating at or below 150 pounds of pressure per square inch (psi).
Two-phase air compressors have two pistons. The first piston compresses the air and pushes it through the valve to the second piston. The second piston compresses the air further and sends it to the storage tank. The two-phase system is found in heavy-duty compressors with ratings above 150 psi.
The air supply is measured in Cubic Feet per Minute (CFM or CFPM) or Standard Cubic Foot per Minute (SCFM). “In general, as the CFM rating is higher, more nails can be placed on the air compressor,” explains William Sadkowski, product manager of Techtronic Industries NA Inc., a manufacturer of Ridgid products.
“For example, an air compressor that supplies 4.4 to 4.9 SCFM can generally support at least two [tools] for framing or roofing,” he says. “A unit rated 10.3 SCFM can support three nailers for trusses or nail guns for roofing. Although this unit can support more tools, it is bigger, it is powered by a gas engine and it is noisier than an electric unit “.
To combine the workforce
In short, you need to know how many nails or staples you can nail with the air stored in the tank and the total capacity of stored air. To ensure proper performance of the air tools, use tools with air requirement ratings below the compressor air supply rating.
“A compressor, in the range of four to five CFPM, generally supports 2 to 2½ men,” explains James Vintzel, group product manager for air compressors at DeWALT.
“An air compressor with 10 CFPM works well with five roofers. The next size range is 16 SFPM and can support eight to nine people working in a multi-family building, “he says.
The larger the tank, the greater the maximum PSI in the tank and the greater the number of nails or staples that the user can drive into a peak or peak base. “This is an important point, as the team does not nail at a constant pace,” Vintzel exclaims.
In the end, choosing the roofing air compressors is reduced to knowing how many contractors are working on the project and how many nailers or staplers or other roofing tools support the air compressor. Let this and the size of the project be your guide.
