The Arion series strainers are more suited to dirty water applications. The dirt is trapped on the inside of the double mesh screens and collects in the bowl. The double port construction of the housing prevents the particles from re-entering the flow stream.
The collected dirt can be flushed directly out to drain by opening the blowdown. The J1521G strainer has a glass collection bowl, while the J1521M strainer has a metal bowl. Standard pressure rating for the strainer is 232 psi / 16 bar. Body connections are 1/2 in / 15 mm NPT and it comes complete with a 3/8 in / 9.5 mm blowdown valve and a discharge tube.
