LEEMIN return oil filter – tank cover mounting, 0.35 MPa signal.

1. Product Introduction

Aite LEEMIN Return Oil Filter is mainly used in hydraulic systems to filter out solid particles and colloidal substances in

 the working medium and control the pollution degree of the working medium. The pollution of the hydraulic system

 directly affects the working quality of the entire hydraulic system.

Aite LEEMIN Return Oil Filter is engineered as a fully interchangeable substitute for original LEEMIN models – maintaining 

identical dimensional parameters, interface specifications, and filtration performance to enable direct drop-in installation

 without any housing modifications. This high-performance return oil filter delivers reliable filtration performance across 

a wide range of industrial applications.

As a professional manufacturer specializing in industrial filtration equipment, we deliver Aite LEEMIN Return Oil Filter

 with stable performance, reliable construction, and competitive pricing for industrial facilities worldwide.

2. Product Features

Aite LEEMIN Return Oil Filter delivers superior performance through the following key features:

2.1 Direct Tank Cover Installation

Aite LEEMIN Return Oil Filter is installed on the oil tank cover – with the filter head exposed outside the oil tank and the 

oil return cylinder immersed in the oil tank. The oil inlet is equipped with pipe and flange connection – simplifying the 

system pipeline.

2.2 Signalling Device for Maintenance Indication

When the filter element of Aite LEEMIN Return Oil Filter is blocked by pollutants, or the system liquid temperature is too low,

 flow pulsation, and other factors cause the oil inlet pressure to be 0.35 MPa, the signalling device will send a signal 

indication – allowing maintenance personnel to replace the filter element promptly.

2.3 High Filtration Precision

Aite LEEMIN Return Oil Filter has the advantages of high filtration precision, large oil passing capacity, small original 

pressure loss, and large dirt holding capacity.

2.4 Simplified System Pipeline

Aite LEEMIN Return Oil Filter features pipe and flange connection at the oil inlet – simplifying the system pipeline and

 reducing installation complexity.

2.5 Reliable System Protection

Aite LEEMIN Return Oil Filter effectively controls the pollution degree of the working medium – protecting the normal

 operation of the hydraulic system.

2.6 Wide Application Range

Aite LEEMIN Return Oil Filter is suitable for metallurgy, thermal power, nuclear power, and textile industries – providing 

reliable performance across multiple applications.

Aite LEEMIN Return Oil Filter offers equivalent performance to genuine LEEMIN parts at 40%–60% lower cost – making it

 an ideal choice for cost-conscious maintenance programs.
