The 652 series FRL line of air preparation products feature high flow characteristics, as well as high- and low-temperature capabilities of -40°C to 80°C. New manifold endplate flanges allow technicians to pull the manifold assembly out of service without disconnecting the piping. The product line is available in three port sizes ranging from ¼ to ½ in. (NPTF, G, or R threads). The series incorporates front-facing and low-profile gauges on its shut-off isolation valves and slow-start/quick-exhaust valves. Other options include integral pressure range indicators, pressure regulator with reverse flow check, and 3-micron pleated pre-filter to the coalescing filters and coalescing filter/regulator combination units.
