Strainer Insert

A filter grid and filter net of stainless steel ensure

long element life. The filter net offers a very high

degree of cleanability.

Housing

The strainer housing is made of special, cold

resistant steel.

Installation / Maintenance

The strainer is designed to resist high internal

pressures. However, the piping system in general

should be designed to avoid liquid traps and

reduce the risk of hydraulic pressure caused by

thermal expansion.

Install the strainer with the cover in downward

position.

Danfoss recommends replacement / cleaning of

the strainer when the differential pressure loss

>0.5 bar (7.3 psi) in the liquid line and >0.05 bar

(0.7 psi) in the suction line. The max. permissible

differential pressure is 1 bar (15 psi).

For further information refer to installation

instruction for FIA.

Danfoss Filters Type FIA80-100 FIA150-200 FIA250-300 Strainers Features

• Applicable to HCFC, HFC, R717 (Ammonia),

R744 (CO 2 ) and all flammable refrigerants.

• Modular Concept:

– Each valve housing is available with several

different connection types and sizes.

– Possible to convert FIA strainers to any

other product in the Flexline TM SVL family

(shut-off valve, hand operated regulating

valve, check & stop valve or check valve) just

by replacing the complete top part.

• Fast and easy overhaul service. It is easy to

replace the top part and no welding is needed

• Filter net of stainless steel mounted direct

without extra gaskets means easy servicing

• Two types of strainer inserts are available:

- A plain insert of stainless steel.

- A pleated insert (DN 15-200) with extra

large surface, which ensures long intervals

between cleaning and low pressure drop.

A special insert (50µ) can be used in

combination with a standard version when

cleaning a plant during commissioning.

• FIA 50 – 200 (2 – 8 in):

A large capacity filter bag (50µ) can be inserted

for cleaning plant during commissioning.

• FIA 80-200 (3 – 8 in) can be equipped with a

magnetic insert for detention of iron particles

and other magnetic particles.

• Each strainer clearly marked with type, size and

performance range

• Housing and bonnet of low temperature steel

in accordance with the requirements of the

Pressure Equipment Directive and those of

other international classification authorities

• Temperature range:

-60 – 150 °C / -76 – 302 °F
