    About Air Preparation
    industrial info icon

    Customize your air preparation system with dryers, filters, and other purifying parts.

    Compressed Air Regulators

    Adjust and maintain the pressure of your compressed air. Install these regulators in your air line after filters.
    Relieving with T-Handle—Gauge Included
    Image of Product. Front orientation. Compressed Air Regulators. Compressed Air Regulators, Relieving with T-Handle—Gauge Included.
    Relieving regulators exhaust when the downstream pressure exceeds the set pressure.
    Regulators with a T-handle are easier to adjust than those with a knob, especially at higher pressures. However, they require more clearance.
    Mounting Brackets—Mounting brackets (sold separately) allow you to attach the regulator to a wall or equipment.

    High-Temperature Pressure-Regulating Valves for Water, Oil, Air, and Inert Gas

    Image of Product. Front orientation. Pressure-Regulating Valves. High-Temperature Pressure-Regulating Valves for Water, Oil, Air, and Inert Gas.
    Rated for more than double the temperature of standard pressure-regulating valves, these can withstand temperatures up to 550° F. They automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range. Valves meet ANSI/FCI 70-2 Class IV for tight shut-off (max. leakage rate of 0.01%).

    Compressed Air Filter/Regulator/Lubricators (FRLs)

    A filter, regulator, and lubricator combined, these FRLs provide clean, lubricated compressed air at your required pressure. The regulator is relieving, so it will exhaust when the downstream pressure exceeds the set pressure.

    Inline with Opaque Bowls

    and Sight Glass

    Inline Components—Inline FRLs are the standard design. Each part can be replaced or repaired on its own, which reduces maintenance costs.
    Aluminum Bowl and Zinc Alloy Bowl—Aluminum and zinc alloy bowls are stronger than plastic bowls, so they won't crack or shatter if they’re dropped.
    Automatic Drain—Bowls with an automatic drain periodically release condensate into the air, eliminating the need for manual emptying.
    Brackets—Mounting brackets (sold separately) allow you to attach the FRL to a wall or equipment.

    Thicker walls and a 304 stainless steel seal make these valves tougher than brass pressure-regulating valves. They automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range. Valves have an internal strainer to trap debris. Body is bronze for durability and a long service life.
