20/21 Series

Product catalog summary

Specifications:
The 20/21 Series Spin-On filters are designed for hydraulic and lubrication oil applications, with a maximum operating pressure of 100 psi (6.9 Bar) and a burst pressure of 300 psi (20.7 Bar) as per NFPA standards. They operate effectively within a temperature range of -45°F to 225°F (-43°C to 107°C). The standard seal material is nitrile, with other options available upon consultation. These filters are compatible with petroleum-based fluids, and synthetic fluid compatibility requires factory consultation.

Design and Dimensions:
The filters feature a thread size of 1.00" - 12 UNF - 2B, with a sealing diameter of 2.79" (70.9 mm) and an element diameter of 3.69" (93.7 mm). The standard element length is 5.27" (133.9 mm), with an extended option of 8.64" (219.5 mm). The dry weight of the standard element is 1.15 lbs. (0.52 kg), and the extended element is 1.72 lbs. (0.78 kg).

Filtration Ratings:
Spin-on elements are available in five filtration ratings: 10 and 25 micron nominal, 3 and 7 micron absolute, and 6.5 micron absolute for water absorptive media. The elements are available in standard and extended lengths.

Pressure Drop Information:
The pressure drop for the 20/21 Series is calculated using a 150 SUS (32 cst) fluid with a specific gravity of 0.9. For other fluids, the pressure drop should be adjusted based on viscosity changes.

Filter Heads:
Purolator filter heads are made from die-cast aluminum and are available with optional pressure and vacuum gauges. The heads are compatible with both suction and return line applications, with various flow rates and port sizes available.

Ordering Information:
The ordering codes for the elements and heads include specifications for media type, element length, bypass valve settings, and gauge port locations. Optional accessories include vacuum and pressure gauges and switches.

Additional Notes:
The document provides detailed dimensional information for filter heads and elements, with conversion instructions for metric measurements. It also includes contact information for Purolator Facet, Inc.
