Suction oil filter – self-sealing valve, large flow, low resistance.

1. Product Overview

Aite Suction Oil Filter is installed at the oil inlet of oil pumps to protect

 oil pumps and other hydraulic components – avoiding suction of polluting 

impurities, effectively controlling system pollution, and improving the 

cleanliness of hydraulic systems. Aite Suction Oil Filter can be installed 

directly on the side of the tank, the upper part, or the bottom – with the

 oil suction cylinder extending into the tank below the liquid level and the 

filter head exposed outside the tank.

Aite Suction Oil Filter is equipped with a self-sealing valve, bypass valve, 

and filter element pollution blocking signal device – ensuring that oil in the

 tank will not flow out when replacing or cleaning the filter element. This

 product features novel design, easy installation, large oil passing capacity, 

small resistance, and easy cleaning or replacement of the filter element.

As a professional manufacturer specializing in industrial filtration equipment, 

we deliver Aite Suction Oil Filter with stable performance, reliable construction, 

and competitive pricing for industrial facilities worldwide.

3. Filter Element Selection Method

Aite Suction Oil Filter element selection follows these key principles:

3.1 Rated Air Intake Requirement

The air flow in the technical parameters of the filter element of rated air intake 

should be greater than the rated air intake of the appropriate engine.

3.2 Filtration Material Requirements

The filtration material has requirements for thickness, tension resistance, 

original intake resistance, and filtration accuracy.

3.3 Filtration Accuracy Requirements

Imported diesel engines require air filtration accuracy of 5μm; domestic diesel 

engines require less than 20μm.

3.4 Filter Element Performance Test

· Flow-Resistance Test – Measurement of air flow pressure loss

· Original Filtration Efficiency Test – Dust collection efficiency of filter element 

can be calculated

· Dust Removal Capacity Test and Cumulative Efficiency Test – For oral paper 

and domestic paper

The selected filter element must match the power, economy, and reliability of 

the original engine.
