Air Compressor Filter Regulator, 3/8" NPT Dual Stage Air-Drying System With 25μM + 5μM Brass Filter Element, Semi-Auto Drain Air Compressor Water Se

About these itemsAll products offer efficient air filtration. They use brass filter elements (e.g., 5μm, 25μm) and sometimes additional sponge or fiber filters. This removes liquid, solid particles, and impurities, ensuring clean air for pneumatic tools.Some models have auto - drainage with a float switch, while others have semi - auto drainage. Both prevent equipment failure from forgotten manual draining.Each comes with a standard NPT connector (1/2", 3/8", or 3/4") to fit most air compressors. Align airflow and clean ports before installation.Constructed with either aluminum alloy bodies or a combination of poly bowl and metal guard. This makes them resistant to pressure, corrosion, and impact for home and industrial use.Many regulate pressure (145 - 175 PSI). Some include desiccant drying for dry air, and one has an oiling port and window for lubrication.Key DifferencesModel NumberTF40 - 04, AWF + AM + AMK40 - 06D, AC3010 - 03, AWF + AM + AMK + AMK40 - 06D, AWF + AM + AMK40 - 04D, AW + AF + AFD3000 - 0303, AF + AF + AR3000, AF4 + AF4 + AR4 + AF5 1/2""TypeSingle - stage filter (TF40 - 04)2 - stage filter + regulator + desiccant dryer (AWF + AM + AMK40 - 06D, AWF + AM + AMK40 - 04D)Filter + regulator + lubricator (AC3010 - 03)2 - stage filter + regulator + double desiccant dryer (AWF + AM + AMK + AMK40 - 06D)3 - stage filter + regulator (AW + AF + AFD3000 - 0303)2 - stage filter + regulator (AF + AF + AR3000)2 - stage filter + regulator + oil - water separation (AF4 + AF4 + AR4 + AF5 1/2"")SpecifacationsTF40 - 04Model: TF40 - 04Filter: 5 μm BrassPort: 1/2"" NPTAir Flow: 140 SCFMMax Pressure: 175 PSITemp: 41 - 140 ℉ (5 - 60 ℃)Material: Aluminum AlloyDrain: AutoWeight: 1.34 lbs (0.72 kg)Dimensions: 2.76 x 2.95 x 8.07 in (70 x 75 x 205 mm)AWF + AM + AMK40 - 06DModel: AWF + AM + AMK40 - 06DType: 2 - Stage Filter + Regulator+ Desiccant DryerFilter: 5 μm Brass + 0.3 μm Sponge + 0.1μm DesiccantPort: 3/4"" NPTAir Flow: 140 SCFMMax Pressure: 175 PSITemp: 41 - 140 ℉ (5 - 60 ℃)Material: Aluminum AlloyDrain: AutoWeight: 6.81 lbs (3.09 kg)Dimensions: 9.45 x 4.33 x 11.81 in (240 x 110 x 300 mm)AC3010 - 03Model: AC3010 - 03Type: Filter + Regulator + LubricatorFilter: 5 μm BrassPort: 3/8"" NPTAir Flow: 70 SCFMMax Pressure: 145 PSITemp: 41 - 140 ℉ (5 - 60 ℃)Material: Metal Guard + Poly BowlDrain: Semi - AutoWeight: 2.03 lbs (0.92 kg)Dimensions: 4.61 x 3.74 x 8.27 in (117 x 95 x 210 mm)AWF + AM + AMK + AMK40 - 06DModel: AWF + AM + AMK + AMK40 - 06DType: 2 - Stage Filter + Regulator+ Double Desiccant DryerFilter: 5 μm Brass + 0.3 μm Sponge + 0.1μm Desiccant x2Port: 3/4"" NPTAir Flow: 140 SCFMMax Pressure: 175 PSITemp: 41 - 140 ℉ (5 - 60 ℃)Material: Aluminum AlloyDrain: AutoWeight: 9.17 lbs (4.16 kg)Dimensions: 12.8 x 4.33 x 11.81 in (325 x 110 x 300 mm)AWF + AM + AMK40 - 04DModel: AWF + AM + AMK40 - 04DType: 2 - Stage Filter + Regulator+ Desiccant DryerFilter: 5 μm Brass + 0.3 μm Sponge + 0.1μm DesiccantPort: 1/2"" NPTAir Flow: 140 SCFMMax Pressure: 175 PSITemp: 41 - 140 ℉ (5 - 60 ℃)Material: Aluminum AlloyDrain: AutoWeight: 6.77 lbs (3.07 kg)Dimensions: 9.45 x 4.33 x 11.81 in (240 x 110 x 300 mm)AW + AF + AFD3000 - 0303Model: AW + AF + AFD3000 - 0303Type: 3 - Stage Filter + RegulatorFilter: 5 μm Brass + 1 μm Fiber + 0.01 μm SpongePort: 3/8"" NPTAir Flow: 60 SCFMMax Pressure: 145 PSITemp: 41 - 140 ℉ (5 - 60 ℃)Material: Metal Guard + Poly BowlDrain: Semi - AutoWeight: 2.76 lbs (1.25 kg)Dimensions: 7.09 x 3.74 x 8.27 in (180 x 95 x 210 mm)AF + AF + AR3000Model: AF + AF + AR3000Type: 2 - Stage Filter + RegulatorFilter: 25 μm Brass + 5 μm BrassPort: 3/8"" NPTAir Flow: 70 SCFMMax Pressure: 145 PSITemp: 41 - 140 ℉ (5 - 60 ℃)Material: Metal Guard + Poly BowlDrain: Semi - AutoWeight: 2.45 lbs (1.11 kg)Dimensions: 7.28 x 3.74 x 6.18 in (185 x 95 x 157 mm)AF4 + AF4 + AR4 + AF5 1/2""Model: AF4 + AF4 + AR4 + AF5 1/2""Type: 2 - Stage Filter + Regulator+ Oil - Water SeparationFilter: 25 μm Brass + 5 μm Brass + 0.3 μm SpongePort: 1/2"" NPTAir Flow: 140 SCFMMax Pressure: 175 PSITemp: 41 - 140 ℉ (5 - 60 ℃)Material: Aluminum AlloyDrain: Semi - AutoWeight: 6.99 lbs (3.17 kg)Dimensions: 13.19 x 4.33 x10.04 in (335 x 110 x 255 mm)
