Focus On: Compressors, Fans & Blowers
Custom-built blower packages address specific needs
This company’s blower packages (photo) are custom built to address specific requirements for elevation, temperature, noise reduction and application. Two models are available: intermediate pressure (15 psig) and low pressure (8 psig). The intermediate-pressure blower packages are designed for semi-dense phase, vacuum loading/pressure conveying and railcar/truck unloading. Low-pressure blowers are made for dilute-phase conveying and silo and hopper aeration. Both models come standard with an inlet filter with service indicator, inlet and exhaust silencers, pressure-relief valve and heavy-duty outlet check valve. All models are mounted on rigid-channel iron frames and are available in three configurations: standard belt drive, jack shaft drive, or direct drive. — Cyclonaire Corp., York, Nebr.
Expanded product line includes new blower
The Panther PD Blower (photo) is a rotary lobe, positive-displacement blower that is designed for either pressure or vacuum applications. Two non-contacting rotors produce vacuum or pressure in an oil-free pumping chamber. The Panther blower features a tri-lobe design to increase efficiency and decrease sound levels. Heavy-duty construction and oil-lubricated bearings on both the gear-end and drive-end of the blower are used. — Busch, Virginia Beach, Va.
Dry compressed air with these membranes
The Balston Smart Dryer 5000 Series membrane air dryers (photo) provide pure, dry compressed air for applications requiring 35°F dewpoints and flowrates up to 600 scfm. This system removes air contaminants down to 0.01 mm. Using sophisticated technology to monitor the air consumption, the system automatically adjusts the regenerative sweep flow as required, without the need for electricity. These dryers are shipped complete with prefilters, auto drains and membrane modules that are assembled in a cabinet with inlet and outlet ports mounted on top for easy installation. — Parker Hannifin Corp., Filtration and Separation Division, Haverhill, Mass.
Extend the life of machinery with clean, compressed air
These refrigerated air dryers provide dry and clean compressed air to extend the life of machinery and reduce downtime and maintenance costs. Series IDFB*E (photo) refrigerated dryers are built with stainless-steel heat exchangers and are UL listed up to sizes for 160-scfm flows. Using environmentally friendly refrigerants (R134a/R407C) to provide a dew point of 37°F, the dryers use a simple control system that incorporates an easy-to-read evaporator gauge. To complement these dryers, the manufacturer also provides main-line filters to remove oil, water and dirt particles in the compressed air. Filtration grades range from 0.01 to 0.3 mm. — SMC Corp. of America, Indianapolis, Ind.
Remove condensate from compressed-air systems
Disposal of compressed-air-system condensate is an environmental concern. The oil/water mixture cannot be discharged directly into sanitary drains, unless the oil is first separated from the water. The Aquamat condensate management system uses a four-stage separation process to automatically separate oil from condensate. The units do not require electricity. Available in six sizes, these units feature an integrated manifold system that allows several condensate lines to be attached to one Aquamat unit. This company also offers a complete line of positive-displacement, rotary-lobe blowers that are available in a number of blower packages. — Kaeser Compressor, Inc., Fredericksburg, Va.
These heavy-duty blowers have been improved
The Whispair blower (photo) reduces noise and power loss through the use of a wrap-around plenum and proprietary jet. Rotation is aided by the jet, which controls pressure equalization and feeds backflow in the direction of impeller movement. Design improvements include repositionable, steel mounting feet and die-cast aluminum drive-end covers and gear covers. These improvements help to reduce installation costs and make maintenance easier, says the manufacturer. — Dresser Roots, Connersville, Ind.
These blowers fit new and retrofitted conveyors
This company’s positive-displacement blower packages (photo) come in models that accommodate dilute-phase, pneumatic conveying situations. Completely self-contained for easy installation, these blowers feature heavy-duty frames and adjustable motor bases, as well as inlet and outlet silencers for a quieter working environment. For safe operation, each has an air filter, relief valve, pressure gage and check valve. — Airlanco, Falls City, Nebr.
Electrically driven gas boosters eliminate contamination
These electrically driven gas boosters offer contamination-free operation at lower cost and smaller size than metal-diaphragm compressors, according to the company. The EDA Series (photo, p.74) eliminates oil migration in applications that use inert gases, including nitrogen, helium, argon, carbon dioxide and air. Unlike compressors, the gas boosters accept a pressurized inlet, allowing them to start under load. The non-lubricated linear bearing assures minimal contamination to the gas, with no need for separation during processing nor conditioning afterward. A gas-seal package allows simple maintenance. With inlet pressures between 750 and 2,600 psi, the boosters provide a maximum outlet pressure of 5,000 psi. They are also available in a two-stage configuration that allows higher gas flowrates with reduced inlet pressures (as low as 450 psi). — Haskel International Inc., Burbank, Calif.
Portable compressors can be rented when needed
A portable, oil-free compressor that is easy to install and operate has been introduced to supplement air needs during equipment shutdowns or breakdowns, or when increased production is needed. The PET 925 (photo), designed for bottle-blowing and PET-industry applications, has a capacity of 925 ft3/min of delivered oil-free air in operating pressures from 350 to 650 psig. The self-contained units include an electrically driven, multistage piston compressor, dryer, discharge filter, cooling tower and other necessary equipment housed altogether on one trailer. With its integrally mounted refrigerant air dryer, the PET 925 can avoid problems of tying into the customer’s dryer. — Prime Energy, a company within the Atlas Copco Group, La Porte, Tex.
More compact and quieter compressors are available
This company designed their new 3700 Series compressors (photo) to make service and routine maintenance faster and minimize production downtime. All standard maintenance can be performed from one side of the machine, and the compressor’s fluid level can be checked without opening the doors. The series also features a fully sealed, environmental-protection pan to capture spills that may occur during servicing. The 3700 Series compressors are compact enough to fit through a standard 36-in.-wide door and operate at a low noise level of 68 dB(A). — Sullair Corp., Michigan City, Ind.
Air-nozzle clusters provide high-blowing force
These new Super Air Nozzle Clusters provide high-blowing force that is suitable for long distance, wide-area blowoff, drying and cooling applications. The engineered clusters are available with four, seven or twelve air nozzles. At full pressure of 80 psig, they have an air consumption of 56, 98 and 168 scfm, while providing strong blowing forces of 3.2, 5.7 and 9.8 lbf. With a zinc-aluminum alloy construction attached to an aluminum body, the nozzles are suited for rugged industrial applications where temperatures can reach 158°F. The noise levels meet OSHA’s maximum allowable noise exposure standard 29 CFR 1910.95(a). — Exair Corp., Cincinnati, Ohio
Use this aeration compressor for wastewater operations
The HST Integral is a fully automated, maintenance-free aeration compressor that self regulates airflow in wastewater and industrial process operations. The high-speed turbocompressor (HST), with frequency converter and magnetic bearings, automatically senses and compensates for surge conditions and maintains a steady aeration flow. The compressor features non-contacting rotating parts, without inlet guide veins or outlet diffusers. The HST design provides oil-free air to an aeration system that helps prevent plugging in the diffusers and will not reduce nor otherwise affect oxygen transfer rates, says the manufacturer. — ABS Pumps, Inc., Meriden, Conn.
This grounding device boosts reliability
When AS motors — commonly used in HVAC/R systems to drive fans, air pumps, chillwater pumps, compressors and other air-handling equipment — are employed with variable-frequency drives, currents are induced on the motor shafts. Without a grounding device, these currents typically discharge through the motor bearings and cause damage such as frosting, pitting, fusion craters and fluting, which can ultimately lead to system failure. The AEGIS SGR conductive microfiber shaft-grounding brush channels harmful shaft current away from the motor bearings to the ground, thereby preventing electrical-bearing damage. The SGR is installed by sliding the brush over either end of the motor shaft and locking it into place with screw-on mounting brackets. The device is available in standard sizes to fit AC motors ranging from 1 to 1,500 HP with shaft diameters from 8 to 153 mm. Larger sizes are available for shafts with diameters greater than 6 in. — Electro Static Technology, Mechanic Falls, Maine
