Mechanical Oil Mist Collector (EJY Series)
Product Classification
Oil mist purifierScope of Application
The EJY series mechanical oil mist collector separates oil mist-containing air through specially designed baffle filters that create impact and sudden airflow direction changes. It uses inertial force separation to capture oil mist and filter large oil droplets or water droplets contained in the contaminated air entering the purification equipment.

Product Overview
The EJY series mechanical oil mist collector is a reliable and easy-to-maintain air purification device designed for machining equipment, cleaning machines and other industrial processing equipment.
It is mainly installed on machine tools to capture oil mist generated during machining processes, helping improve workshop air quality and protect operators from harmful airborne contaminants.
The EJY series adopts a mechanical separation technology. Oil-mist-containing air impacts specially designed baffle filters or changes airflow direction rapidly. Through inertial force separation, oil mist and larger oil droplets or water droplets are effectively captured and removed from contaminated air.

Working Principle
The EJY series mechanical oil mist collector adopts a multi-stage filtration system to gradually improve filtration accuracy and achieve efficient oil mist collection.
The first-stage filter captures oil mist particles larger than 10μm. The second-stage filter collects oil mist particles above 3μm. The third-stage filter further captures oil mist particles above 1μm. A high-efficiency filter can also be installed at the rear stage to collect smoke generated during machining processes.
Driven by the built-in fan, oil mist enters the first-stage stainless steel demister. The layered metal mist elimination mesh captures oil droplets through airflow collision. The collected droplets combine into larger oil drops inside the filter mesh and flow back into the oil collection tray under gravity.
The second-stage filter cotton increases filtration area and reduces airflow speed, allowing remaining oil mist particles to be further captured and recycled.
The centrifugal impeller operates at high speed and uses centrifugal force to separate oil particles again, allowing collected oil to return to the oil tank.
The third-stage filter cartridge captures fine oil mist particles and effectively protects the aluminum housing motor. The optional high-efficiency filter further removes trace smoke generated during machining.
Key Features
- Multi-stage filtration design improves filtration accuracy and efficiently captures oil mist particles.
- Stable and reliable operation: Equipped with a balanced built-in centrifugal impeller with balance accuracy of 0.2mm/s, IP54 high-protection aluminum motor and thermal protection device for long-term stable operation.
- Low maintenance cost: Compared with electrostatic oil mist collectors and media filtration systems, the EJY series provides lower maintenance requirements.
- Low-noise operation: Vibration reduction design between mounting brackets and equipment structure, combined with direct-drive low-noise motor, effectively reduces operating noise.
- Compact structure and flexible installation for different machining environments.
Humanized Design
The EJY series features simple installation and convenient maintenance.
Based on a classic industrial design concept, the equipment provides low vibration, low noise operation, flexible installation and strong adaptability. It is equipped with power indicators, circuit protection, independent switches and user-friendly maintenance design.
