IFS-R4

Product catalog summary

Overview

The IFD-R4 Series consists of inline duplex filters designed for industrial fluid filtration. These filters feature a double body with cartridge-type filter elements and operate with an outside-to-inside flow direction.

Technical Specifications

Maximum Flow Rate: 4500 liters per minute (1190 gallons per minute)
Maximum Operating Pressure: 25 Bar (362.5 psi)
Operating Temperature Range: -30°C to +90°C (-22°F to +194°F)
Connections: ANSI, DIN, UNI standards
By-pass Valve: Not included
Filter Element Types: Microglass fiber (3, 6, 10, 25 µm), Cellulose (10, 25 µm), Wire mesh (10 to 250 µm)
Materials: Carbon steel, stainless steel (AISI 304, 304L, 316, 316L); seals made of Buna-N or Viton compatible with various fluids as per ISO 2943
Pressure Collapse Rating: 20 Bar (290 psi) according to ISO 2941
Indicator: Differential visual electrical indicator set at 2 Bar (29 psi)
Balancing Valve: Calibrated orifice diameter 3 mm
Davit: Provided for flanges weighing over 15 kg

Dimensional and Flow Data

Filter sizes range from DN 10 to DN 31, corresponding to nominal diameters from 2" to 8". Flow rates are based on a 25 µm microglass fiber cartridge with mineral oil (density 0.86 kg/dm³, kinematic viscosity 30 cSt) and a maximum pressure drop of 0.35 bar (5.075 psi) at full filter load.

Dimensions and weights vary by model, with oil volumes ranging from 50 to 320 liters and cartridge counts from 1+1 to 3+3 depending on size.

Valve and Connection Options

Foot-mounted flanged filters with 2x3-way ball valves or 6-way autoclave valves
Connection port types include flanges per UNI EN 1092-1, ANSI, and DIN standards with pressure ratings PN 10, PN 16, ANSI 150, ANSI 300, etc.

Filter Media and Efficiency

Microglass fiber cartridges with beta ratios (b) greater than 200 for 3, 6, 10, and 25 µm ratings
Resin impregnated cellulose cartridges with beta ratios greater than 2 for 10 and 25 µm
Wire mesh cartridges available in multiple micron ratings without specified beta ratios

Ordering Information

Ordering codes are structured to specify:

Nominal size (DN)
Filtration rating (micron size and media type)
Seal material (Buna-N, Viton, Teflon, or asbestos-free)
Connection port size and type
Indicator type (none or differential electrical visual gauge)
Housing material (carbon steel or stainless steel variants)

Electrical and Indicator Specifications

Indicator voltage: 230 V
Amperage: 10 A
Switch type: SPDT (Single Pole Double Throw)
Maximum ratings: 28 VAC 0.25 A, 28 VDC 3 W
Connector: DIN 43650

Key Recommendations and Limitations

Selection of filter size must consider flow rate and connection type
Flow rates are based on mineral oil with specific density and viscosity; performance may vary with other fluids
No by-pass valve is included, so filter clogging must be monitored via the differential pressure indicator
Pressure collapse rating limits maximum differential pressure across filter elements to 20 Bar
