Product Description

SMC modular-type F.R.L. combination unit.
[Features]
· Uses a transparent bowl guard.
· A transparent bowl guard with improved environmental resistance that provides all-round protection.
· The manufacturer has removed the window from the bowl guard and instead covered the entire internal bowl with a polycarbonate transparent bowl guard.
· Now, even if the environment changes and the bowl is exposed to corrosive chemicals or oil, the foreign matter will not stick directly to the pressurized bowl. This can help reduce the risk of the bowl breaking.
· Superior visibility: 360°
· The use of the transparent bowl guard allows you to check the status of the drain inside the filter bowl and to check the amount of residual oil in the lubricator from any angle.
· Weight reduction: reduced by up to 90 g
· Without corrosion. The use of a resin body ensures there is no rusting.

*1: Options G and M are not assembled and are supplied loose at the time of shipment.
*2: When pressure is not applied, condensate which does not start the auto drain mechanism will remain in the drain bowl. Therefore manual release before ending operations is recommended.
*3: If the compressor used is small (0.75 kW, discharge flow rate is less than 100 L/min [ANR]), air leakage from the drain cock may occur when operations start. As such an N.C. type is recommended.
*4: When the pressure gauge is attached, a 1.0‑MPa gauge will be fitted for the standard (0.7‑MPa setting) type; and a 0.4‑MPa gauge for the 0.2‑MPa type.
*5: The bracket position varies depending on the T-spacer and pressure switch mounting.
*6: Make sure that the outlet pressure is released to atmospheric pressure using a pressure gauge. For the V1 specification, use the regulator with a set pressure of 0.15 MPa or more to ensure the pressure release.
*7: Pressure can be set higher than the specification pressure in some cases, but use with the pressure within the specified range.
*8: Does not include a valve function.
*9: Thread type NPT is applicable. Under new Japanese measurement laws, this product is only available for sale outside of Japan (SI units are used in Japan).
However, the pressure switch offers dual unit presentation in both MPa and psi.
Round-type Pressure Gauge (with Color Zone): cannot be used in combination with M. Available on request as separate, special order from the manufacturer.
*10: ○ is for thread type NPT only.
*11: Metal bowl: Cannot be selected in combination with 2, 8.
*12: Float type auto drain: Cannot be selected in combination with C, D.

*1: Conditions: Mist separator inlet pressure is 0.7 MPa. The rated flow varies according to the inlet pressure.
Keep the air flow within the rated flow to prevent an outflow of oil to the outlet side.
