Data Sheet
Strainer housing
Type FIA 65
Reliable ltration up to 65 bar
FIA strainers are a range of angleway and
straightway strainers, which are carefully
designed to give favourable ow conditions.
The design makes the strainer easy to install,
and ensures quick strainer inspection and
cleaning.
FIA strainers are used ahead of automatic
controls, pumps, compressors etc., for initial
plant start-up and where permanent ltration
of the refrigerant is required. The strainer
reduces the risk of undesirable system
breakdowns and reduces wear and tear on
plant components.
FIA strainers are equipped with a screen mesh
of stainless steel, available in sizes 100, 150, 250
and 500μ (microns*), (US 150, 100, 72, 38
mesh*).
* Mesh is the number of threads per inch. μ
(microns) is the distance between two threads
(1μ = 1 /1000 mm).

Strainer housing, type FIA 65
Features
• Modular Concept:
◦ Each valve housing is available with DIN and ANSI butt weld connection and in several dierent sizes.
◦ Possible to convert FIA strainers to any other product in the SVL family (Shut-o valve, regulating valve, check &
stop valve or check valve) just by replacing the complete top part.
• Quick and easy maintenance. Replacement of top part does not require welding.
• Filter net of stainless steel mounted direct without extra gaskets means easy servicing.
• Two types of strainer inserts are available:
◦ A plain insert made of stainless steel.
◦ A pleated insert (DN 15-200) with extra large surface, which ensures long intervals between cleaning and low
pressure drop.
• FIA 15-40 (½ – 1 ½ in.):
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 lter bag (50μ) can be inserted for cleaning plant during commissioning.
• FIA 65-200 (2½ - 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 classication authorities
• Classication: DNV, CRN, BV, EAC etc. To get an updated list of certication on the products please contact your
local Danfoss Sales Company.
• Equipped with 42CrMo5 bolts to withstand high pressure.

Refrigerants
Applicable to HCFC, HFC, R717 (Ammonia), R744 (CO₂) and ammable refrigerants.
For further information refer to the product instruction for FIA.
New refrigerants
Danfoss products are continually evaluated for use with new refrigerants depending on market requirements.
When a refrigerant is approved for use by Danfoss, it is added to the relevant portfolio, and the R number of the
refrigerant (e.g. R513A) will be added to the technical data of the code number. Therefore, products for specic
refrigerants are best checked at store.danfoss.com/en/, or by contacting your local Danfoss representative.
