Each and every one of our piston air compressors is built to exacting standards, to provide years of dependable service, under demanding conditions. And because we use only high-quality brand-name components, we offer an extended five year warranty, on all of our piston air compressors.
At the core of our Whisper Series Quiet Air Compressors is our sturdy and reliable air compressor pump by Eaton Compressor. These air compressor pumps are exceptionally quiet in operation and engineered to provide years of reliable service.
Our air compressor pumps are engineered with reliability and durability in mind. The crankcase is solid cast iron, ensuring stable crankshaft alignment and the ability to handle a higher workload even under heavy load conditions. Our compressor pumps also feature a precision balanced solid cast iron crankshaft with Timken-Style stainless steel roller bearings on the front and rear of the crankshaft, ensuring smooth & efficient operation with less drag and reduced energy usage
In summary, not only do we have one of the highest-quality, most durable air compressor pumps in the industry, we can also boast the lowest RPM air compressor pumps on the market. On the majority of our compressors, we purposefully oversize our pumps, running them at lower RPMs than most manufacturers. Our more powerful, low RPM pump can still yield a high CFM output, because both our bore and stroke are larger. The benefit is that our customers get the big CFM output, while enjoying the lower RPM operation, which reduces friction and heat, extending the life of the air compressor pump.
Our 5hp air compressor pump has large Timken-Style roller bearing on the crank ends on each end of the crankshaft. This ensures good crank stability and long compressor bearing life. Each cylinder is all cast iron with no sleeves or aluminum. All cast iron prevents cylinder distortion and egg-shaped cylinders when pump gets hot. This pump has 2 B-Section belt drive. Twin belt ensures better belt gripage and longer belt life. Our 5 hp air compressor pump has head unloaders. This is very nice for continuous run applications such as gasoline driven or electric driven high duty cycle applications. Head unloaders are an air cylinder in each head. When air is applied to them, they open or push the intake valves open allowing the pump to go into a free wheel mode. The cylinders are still moving in a free wheel mode, but it cannot compress the air because the intake valve is held open. This pulls cool air into the cylinder. The cool air absorbs the heat in the pump and blows it back out the intake valve. This is nice when you are sandblasting, etc., under heavy duty cycles. This pump has a site glass to view your oil level.
I bought one of these pumps in 2012 put it in my shop, I have a 10 horse v 4 cylinder compressor at the house, the pump is a Polar pump. I was going to switch air compressors. But the 5 horse did better than I expected and supplied enough air for my shop so I never switched them. If had known the 5 horse would put out that much air, I would have made the 10 horse a 5 horse. By the way the 10 horse with a 120 gallon tank that is empty will pump up to 180 pounds of air pressure in 5 1/2 minnuts, I thought that was very impressive. 2b1af7f3a8
