EMAX Industrial Plus Silent Air piston compressors are quiet. The most common complaints about compressors are their high noise levels. EMAX Silent Air units not only still the noise, but they also do it with a big cfm output and lower rpm. Featuring their Whisper 100 system installed on the back of the tanks, stationary compressor dB ratings are reduced by as much as 25 percent. The Whisper dissipates compressor intake noise by channeling intake air through a series of baffle plates and prefilter media inside the silencer cabinet. Piston intake noise is trapped and dissipated within the silencer structure; plus, it also provides secondary filtration for cleaner air. Industrial Plus Silent Air piston compressors are designed for up to 50,000 hours of commercial or industrial use with proper maintenance. At the core of these extremely durable compressors are super-quiet pumps featuring cast iron crankcases, precision-balanced cast iron crankshafts, and high-quality stainless steel roller bearings to ensure smooth, efficient operation. For long life and rebuildability, EMAX adds steel connecting rods with replaceable rod bearing inserts, removable cast iron cylinders and cylinder heads, disc intake and exhaust valves, and cast iron flywheels with a built-in fan. These bigger low-rpm pumps have a larger bore and stroke, so you get big cfm output with reduced friction and heat buildup. All EMAX Industrial Plus compressors have low-rpm motors (1,750 rpm). Because of their higher torque factor, compared to the 3,450 rpm motors most manufacturers use, they run much cooler. They also yield low harmonic distortion, provide much higher torque in cold weather starting, and require less electricity to start. Other features include big 1 3/8 in. output shafts, large starting and running capacitors, and dynamically balanced armatures. Their 15 Service Factor means the motors can be pulled 15 percent over full load. Depending on the application, many Silent Air piston compressors feature totally enclosed, fan-cooled (TEFC) motors that keep harmful dust and particulates out of the motor. This allows them to be used in dusty commercial and industrial environments without worrying about maintenance. They have 100 percent copper windings with pre-wired magnetic starters (necessary on any motor over 15 amps). These are high-quality, name brand, premium efficiency motors that meet all UL and CSA requirements. Some lower horsepower models are equipped with name brand, open-drip (OPD) motors. The running and starting windings on these motors are all 100 percent copper-wound for premium efficiency, reliable performance, and durability. These units also meet all UL and CSA requirements and include pre-wired Condor combination starter and pressure switches with actuation-type diaphragms. EMAX Industrial Plus Silent Air piston compressors also feature: * Head unloaders allow for load-less starting and can help cool the pump in high-duty cycle applications * Built-in inter-coolers and after-coolers * Raised-pump mounting platforms that open the underside of the crankcase to cooling air flow * Automatic belt tensioners for much easier and quicker adjustments and alignment * Selectable continuous-run or automatic start/stop operation to maximize performance and reduce wear * OSHA-approved belt guards for your safety * ASME code-compliant tanks * Dual-timer automatic tank drains eliminate maintenance * Taper lock 2-groove pulleys * Dual 2-groove belts for long life and low vibration * Extended tank water drain pipes plumbed to the front with 1/4 in. ball valve handles * 100 percent brass check valves, safety valves, and ball valves * Top-quality plumbing fittings

These motors meet all UL and CSA requirements and include pre-wired Condor combination starter and pressure switches with actuation-type diaphragms. EMAX uses only taper-lock style, 2-groove pulleys with dual 2-groove, B-style belts to drive their pumps. Dual belts ensure long belt life with low vibration for smoother, quieter operation because dual belts do not have to be as tight as a single belt. Tighter belts put more load on the compressor pump and the motor bearings; that decreases the life of both. Much better than a fixed bore pulley with a set screw; the taper-lock design locks the pulley in position on the motor shaft preventing it from loosening or moving. EMAX piston compressors also feature: * Head unloaders allow for load-less starting and can help cool the pump in high-duty cycle applications * Built-in inter-coolers and after-coolers * OSHA-approved, 13-gauge steel, expanded metal belt guards * ASME code-compliant tanks * Extended tank water drain pipes plumbed to the front with 1/4 in. ball valve handles * 100 percent brass check valves, safety valves, and ball valves * Top-quality plumbing fittings * Big 1 3/8 in. output shafts * 15 Service Factor motors can be pulled 15 percent over full load
