The only defense your expensive equipment has against destructive air contaminants is you air intake filter system. NAFCO manufactures a full line of panel and cartridge air intake filters and housings. NAFCO air intake filters can handle air flows up to 100,000 scfm and are available in efficiencies from 0.3 µm absolute to 40µm.
Intake Air Filter Features
  • Low pressure drop
  • Long service life
  • Easy filter change-out maintenance
  • Absolute protection of downstream equipment

    NAFCO filter housings are constructed from rugged welded steel and offer a long service life installed outdoors or indoors. Housings can be mounted directly to equipment or inlet piping (connection sizes from ½’’ to 60’’).

    Crystal-Line Intake Air Filter System
    NAFCO’s Crystal-line intake air filter system helps remove corrosive chemical contaminants from compressed air. Trace quantities of hydrogen sulfide, benzene, and other chemical contaminants are present in the air around industrial sites. These chemicals create corrosion and damage compressor internals and downstream equipment.

    Crystal-line 4-Stage System
  • Stage 1 – 10 µm 98% efficient pre-filter
  • Stage 2 – Two Crysral-line filter media panels. Panels are selected to address specific air contaminants.
  • Stage 3 – 4 µm 98% efficient filter behind crystal-line panels to protect stage 4 final filters
  • Stage 4 – 0.3 µm 99.7% efficient final filter

    Crystal-line Technology
    Crystal-line media contains impregnated zeolite and impregnated activated carbon. Model CLI uses potassium permanganate to adsorb corrosive gases through oxidation. Model CLI is low dusting. Compared to competitive alumina chemisorbents CLI produces 90% less dust. Model CLII features impregnated activated carbon specially enhanced to remove selective acid gases and chlorides. CLII uses a high quality coconut shell granular activated carbon with a surface area if 1100 M2 per gram.

  • Aftercooler/Separators
  • Air receivers
  • Coalescers (pre-filter)
  • Refrigerated dryer blow-down
  • Drip legs
    Removing water and sludge with an automatic drain valve helps your compressed air system run more efficiently reducing your utility cost.

    Air System Products, Inc. (ASP) Drain Valves
    Sure-Drain
    The Sure-Drain is an optimized ball valve. Ball valves reliably drain unwanted accumulations from air systems. The straight through flow and positive closing action delivers trouble-free operation. The Sure-Drain uses a small coupling to connect the ball valve to the gear motor eliminating any small misalignments and reducing the risk of premature ball valve failure. Drain cycles can be set between 1 and 50 minutes. The valve opens for 5 seconds each cycle. Timing is controlled via a simple programmable solid state timing control accessible from the outside.
    Features
  • External controls (1 – 50 minute cycle adjustability)
  • 600 psig maximum working pressure, no minimum required
  • Sizes: ¼’’, ½’’, Ύ’’, 1’’ASP's Sure-Drain valve

  • Non-corrosive NEMA 4 enclosure
  • Universal mounting position
  • Solid state timer
  • Electrical: standard 115V, 60 Hz
  • Approximate weight: 6 lbs


    Posi-Drain
    Air Systems Products Posi-Drain drains water, oil sludge, and scale from filters, air receivers, dryers, separators, aftercoolers, and other compressed air system equipment. The Posi-Drain works dependably in heavy contaminant applications such as compressed air condensate draining because of its self-cleaning valve and straight through flow design.
  • Self Cleaning Action - Each time the plunger moves up and down the face of the valve seat is wiped clean by the seal disc.
  • Straight Through Design - When the solenoid is energized, the plunger and seal are lifted so that the condensate flows straight through. Other solenoid valve designs force contaminants to travel in a dirt catching “S” shaped flow.
    Features
    ASP's Posi-Drain valve
  • Adjustable drain cycle: 5 seconds to 50 minutes. Valve open period: 1 to 15 seconds
  • Indicator lights for power on and valve open

    Air Receivers
    air receiverFluid Energy Industrial can work with you to select the right receiver and have it manufactured to your specifications at practically any size in diameters manufacturing air receiversfrom two inches to 12 feet. A large line of stock air receivers and custom air receivers with special fixturing, internal weldments, and tight tolerances are available. Both coded and non-coded tanks are available. Fluid Energy Industrial will work with you to meet any special local codes. In general at a minimum, local codes require air receivers to be ASME coded vessels.

    Aftercoolers
    Aftercoolers can cool compressed air flows from 35 to 4,000 scfm to within 10°F approach of the ambient air temperature for air-to-air exchangers and 10°F approach of inlet air temperature for shell-and-tube exchangers. PPC's aftercoolers are rated to 400°F and 250 psig with a maximum pressure drop of 3 psi. Used with an oil/water separator and an automatic drain valve an aftercooler will remove up to 90 percent of the water in a compressed air system.

    Mist Eliminators
    mist eliminator
    Sentry Mist Eliminators
    Problem: Compressed air system coalescing and particulate filters cannot handle excessive water and oil loads. It is common for the amount of moisture exiting the aftercooler to exceed 200 PPMw. Most traditional coalescing filters are not efficient when challenged with loads greater than 20 PPMw.

    Solution: Sentry Mist Eliminators can easily handle 200 PPMw. Actually, the Sentry Mist Eliminator can remove 99.5% of all liquid loads up to 30,000 PPMw.

    How it Works: The thick packed-bed filter design continuously drains itself as liquids coalesce, quietly dropping to the sump for draining. Face velocities are extremely low virtually eliminating the possibility of liquid re-entrainment.
    Benefits
  • Particulate Removal - Removes 100% of all particles 3µm and greater. 99.5% removal efficiency of all particles down to 0.1µm. The Sentry Mist Eliminator has an unparalleled ability to remove both particulate and liquid from compressed air streams.
  • Low Pressure Drop - Sentry Mist Eliminators have pressure drops of less than 1 PSID, often for more than 10 years. Sentry mist eliminators can last 10 to 20 times longer than conventional cartridge filters.
  • Low Operating Cost - Using a conservative assumption that Sentry Mist Eliminators will reduce pressure drop 3 PSID as compared to conventional cartridge filters, a 1.5% efficiency gain can be achieved. For a typical 5,000 SCFM system, energy savings can easily exceed $6,000 per year and more, depending on the cost of energy.

    Oil/Water Separators
    Carryover oil from oil-lubricated compressors exits the compressed air system with the condensate produced at aftercooler/separators, wet air receivers, coalescing filters and refrigerated air dryers. The EPA has found oil latent condensate is unsafe to discharge to surface waters, sanitary sewers, or waste treatment facilities. Oil is only a small portion of the condensate. By using an oil/water separator you can remove oil from condensate allowing the discharge of the water portion by conventional means. The oil still needs to be properly disposed of, but at a much lower cost than the original large volume of oil and water condensate.

    Intermediate Controllers
    Intermediate controllers, also known as demand controllers or pressure flow controllers, are essential in eliminating artificial demand in your compressed air system. Installed downstream of a large supply side pressure vessel, the demand controller accurately controls the pressure to the demand side of the plant. With this configuration, the compressors can run at the most efficient pressure and handle the base demand controller, intermediate controllerload requirement for the plant while the useable storage handles peaks in demand. All other compressors can then be shut down.

    Because the demand controller responds much faster to changes in plant pressure than compressor controls do, large demand side pressure swings are eradicated. Higher pressure causes a system to use more air, so by controlling pressure swings you eliminate artificial demand. Installing one controller can help reduce your overall operating cost.

    Cost reduction opportunities exist on both the supply and the demand side of a compressed air system, but 2/3 of those opportunities are present on the demand side out in the plant, and generally require low capital expenditures.

    To give an example of how substantial the savings can be from reducing your compressed air operating costs, think in terms of product sales vs. operating costs. Increasing sales annually by $1,000,000 at 10% profit has the same value as reducing operating costs on the compressed air system by $100,000. Reducing your operating costs by $100,000 can be easier done often than increasing sales by ten times that amount. Since the average cost to operate a compressor is $55,000 annually, and considering that most plants have multiple compressors, you can see the potential to optimize air efficiency and save money. Installing an intermediate controller in your compressed air system is a good step towards reducing your plants compressed air costs.

    Intermediate Controller Features and Benefits
    Feature Benefit
    Straight through design Straight through flow path on the primary valve
    All welded construction Eliminates pressure drop through fittings
    Longer radius elbows Improved by-pass performance
    I-P transducer is positioner mounted Signal between the control panel and the positioner is electronic instead of pneumatic for faster response
