DRYERS & FILTRATION
Dryers range from refrigerated to regenerative desiccant type and filters range from particulate coalescing types. All are designed for maximum reliability to protect critical production processes with clean, dry air.

Refrigerated Air Dryer:
Cycling: Full cycling design saves energy by turning the dryer ON & OFF in response to real time operating conditions. Average 43% full load power savings over heavy mass dryers. Average 37% full load power savings over most conventional designs.
Non-Cycling: Non-Cycling dryers maintain constant pressure dew points as low as 35°F. Utilizing air to air heat exchanger and air to refrigerant heat exchanger.
High Inlet Temperature: Incorporates a built-in aftercooler, which allows the system to handle inlet temperatures as high as 250°F. While the dryer capacity is rated at 180°F inlet.
Variable Speed: Variable Speed Refrigerated Air Dryers combine state-of-the-art variable speed drive technology with dual action heat exchanger design. In addition, the SVSD variable speed drive uses microprocessor-based controls to reduce the compressor's power consumption at reduced loads while providing consistent dew points.
Desiccant Dryers:
Heatless Regenerative: Dual tower desiccant dryers have compressed air pressure dew points ranging from -40°F to -100°F. Heatless dryer uses approximately 15% of the clean dry compressed air to purge the saturated off line desiccant bed.
Heat Regenerative: Works on the same principal as the Heatless units. However, they are equipped with an internal or external heater which heats the saturated off line desiccant bed to remove compressed air moisture and reduces the purge air by approximately 7%.
Blow Purge: Blow Purge dryers use an external blower and heater to generate the purge air to remove the moisture from the saturated off line desiccant tower.
Filtration:
Particulate Filters: Remove harmful oil/water condensate, pipe scale, dirt and rust from the compressed air system. Particulate elements are rated for 40 or 5 micron. Particulate filters are installed upstream of regulators to prevent valve failure. They are also used as pre-filter to oil removing and coalescing filters to insure high efficiency and long element life.
Oil Removing Filters: General industrial filters with low pressure drop and long element life. The element offers a very good level of oil removing capacity down to .9 micron.
Coalescing Filters: High filtration of oil aerosols and sub micron particles. Removal of particles down to .01 micron. Often used with instrumentation, paint spraying and where air blows on the finished product.
Activated Carbon Filters: Removal of oil vapor and hydrocarbon odors giving a maximum remaining oil content of .003 PPM. To insure proper filtration, the activated carbon filter should not be installed without a particulate and coalescing filter upstream.
Regulators: Designed to reduce and maintain the downstream air pressure to a given piece of equipment. There are two basic types:
1. Relieving regulators which can be adjusted from a higher pressure to a lower pressure. Relieving regulators exhaust the downstream air pressure through the regulator itself.
2. Non-Relieving regulators will not allow the air pressure to escape from the regulator. The air must be exhausted downsteam by a valve or air gun. Most general purpose regulators are adjustable from 0 to 125 PSI. Other pressures are available upon request.
Lubricators: Designed to inject lubricating oil in aerosol form into the compressed air steam. The aerosol helps lubricate pneumatically operated equipment such as air tools, valves and cylinders - reducing maintenance cost and extending equipment life.
Most standard lubricators are Fog-type, which produce oil particles as large as 2.5 micron fog droplets. The entire droplet is injected into the air stream helping to lubricate the intended equipment. Ultrafog or Micro-fog lubricators produce oil particles as small as .4 micron. The oil droplet is atomized to a fine mist and is collected in the area above the oil in the bowl before sending the lighter particles down stream. Ultafog or Micro-fog lubricators are designed to suspend the lighter oil particles in the air stream for long distances.

Maine Air Power, Inc. offers Portable and Stationary Breathing Air Purification Systems.
Standard compressed air Usually is contaminated with oil, water, dirt, rust and often deadly (CO) carbon monoxide. Systems with four or five stages of purification will remove or reduce these contaminates and continually monitors the carbon monoxide level of the purified air to QSHA Grade D breathing air specifications.
Types of applications to use breathing air purification systems: painting, sand blasting, insulating, welding, toxic spills, asbestos abatement, tank cleaning/inspection, sewer work/manholes and foundries.
