Filter drier with sight glass

The filter type FGU with sight glass welded have been designed to semplify the installation of the filter and the sight glass on the refrigeration and conditioning systems. They allow reduction of time, halving the number of soldering and avoinding space problems. The use of 100% molecular mesh makes the filters compatible with most of refrigerant flu ids and allows maximum absorption of humidity even at high temperatures which would not be possible with the addition of silica gel and active alumina. The entire line has been de signed for use with almost all of the refrigerants present on the market, i.e. fluids classified in Article 13, paragraph 1, letter (b), of Directive PED 2014/68/ EU as part of Group 1 and Group 2; most of these fluids are indicated in Annex E of standard EN 378-1 as Class A1, A2L and A3. All the filters are nitrogen pressure tested to ensure a perfect fit. FGU range filters are epoxy-polyester powder-coated to ensure perfect resistance to corrosion in saline chamber for 350 hours.

Materials
The filter body is stainless steel. The flare connection unions are in copper steel while the unions to be welded are in copper steel or copper (5/8-3/4-7/8 inch) A net and a filter cloth at the outlet of GAR range FG filters en sure the elimination of 20 micron mechanical particles.

Installation
The installation orientation can be both vertical or horizontal, but GAR suggests vertical with flow direction pointing down, to avoid stagnation of fluid.
The direction of the flow must be in accordance with the arrow on the label.

Operating conditions
Ts -40°C + 80°c Ps max 45 bar
Refrigerant fluids HFC, HFO, HC, blends

For use with fluids other than those explicitly indicated, please contact GAR srl
