Introduction

CFIA filters are a range of angle-way and straight-way filtets which are carefully designed to give favourable flow conditions.The design makes the filter easy to install,and ensure quick filter inspection and cleaning.

CFIA filters are used ahead of automatic controls,pumps, compressors etc.for inntial plant start-up and where permanent flitration of refrigerant is required.The filter reduces the risk of undesirable system breakdowns and reduces wear and tear on plant components.

CFIA filters are required with a screen mesh of stainless steel,available in sizes 100,150,250 and 500μ(microns*), (US 150,100,72,38 mesh*) .

Features

Appliable to all common refrigerants and all noncorrosiv gases/liquids.
Filter net of stainless steel mounted direct without extra gaskets means easy servicing.
CFIA fliter housing compatible with housings belonging to other Castle products.A compatibility overview can be obtained from local Castle Distributor.
Mesh is the number of threads per inch. μ(microns)is the distance beween two threads 1μ=1/1000mm).
CFIA 50-200(2-8in.)can be equipped with a magnetic insert for detention of iron particles and other magnetic particles.
Each filter clearly marked with type,size and performance range .
Housing and bonnet of low temperature steel.
Temperature range -46°C/+150°C .
Pressure range:CFIA:40barg(580psig)
