39911631 Ingersoll Rand Product Overview
First, the 39911631 Ingersoll Rand hydraulic filter stands as a core component for heavy-duty hydraulic systems. Moreover, it delivers high-precision filtration for Ingersoll Rand compressors and matched industrial equipment. In addition, it removes harmful contaminants to protect pumps, valves and actuators from abrasive wear.
Working Principle of Hydraulic Filtration
Fluid Flow & Contaminant Capture
To start with, hydraulic oil enters the filter housing under system pressure. It flows from the outer perimeter toward the central core of the pleated filter media. Meanwhile, the multi-layer glass fiber media uses three key mechanisms to trap impurities.
First, direct interception blocks particles larger than 11 microns, matching the filter’s Beta 1000 efficiency rating. Second, inertial impaction catches heavy metal fragments as oil changes direction through fiber gaps. Third, diffusion capture retains tiny particles via Brownian motion within the media structure.
Filtration Performance & Media Design
Next, the pleated construction maximizes surface area for extended dirt-holding capacity. It maintains consistent oil flow while capturing contaminants without excessive pressure drop. Furthermore, the media’s Beta 1000 rating at 11 microns ensures 99.9% removal of targeted particles. This level of efficiency prevents component scoring and extends hydraulic system service life.
Sealing & System Integration
In addition, the filter’s precision-machined gasket creates a leak-proof seal between housing and element. The 1 3/4-12 UN thread provides secure mounting for stable operation under vibration. Clean, filtered oil exits through the central tube and re-enters the hydraulic circuit, completing the purification cycle.
Ingersoll Rand Hydraulic Filter Complete Technical Specifications
Dimension & Structural Data
To begin with, this filter features fixed dimensions for perfect fitment. It has an outer diameter of 119.38 mm (4.70 inch) and a total length of 295.4 mm (11.63 inch). Meanwhile, it uses 1 3/4-12 UN thread for reliable installation. Its gasket measures 86 mm OD and 79 mm ID to ensure tight sealing in all operating conditions.
