AF‑22 AF‑35 Air Filter
Product Overview
AF‑22 AF‑35 Air Filter is a tank‑mount breather FILTER, installed on the top of hydraulic oil reservoir for the hydraulic system. This practical FILTER allows air to flow in and out of the tank while intercepting dust, grit and external impurities, preventing contamination of hydraulic oil for various industrial and mobile Machine. It maintains balanced internal tank pressure, avoids vacuum or over‑pressure damage to the reservoir and improves the service life of the whole hydraulic system .

Working Principle
As an essential FILTER for the hydraulic system, when the oil level inside the reservoir rises and falls during Machine operation, air passes through this breather unit. Dust and solid particles from ambient air are trapped by the metal‑mesh filter media before entering the oil tank. The built‑in structure prevents hydraulic oil from splashing out. It keeps tank pressure stable and protects hydraulic components from particle‑induced wear inside the hydraulic system.
Core Advantages
1. Compact tank‑top mounting design, simple installation for the hydraulic system.
2. Two models AF‑22 and AF‑35 to match different air‑flow demands of different Machine.
3. Robust metal mesh media, good dust‑blocking performance and anti‑splash function.
4. Simple structure, easy to inspect and clean the FILTER; low maintenance cost.
5. Wide temperature adaptability, suitable for workshop and outdoor harsh working conditions.
Application Range
This AF‑22 AF‑35 FILTER is widely fitted on the oil tank of the hydraulic system for construction machinery, injection molding machines, machine tools, metallurgical equipment and other industrial Machine. It is widely used for hydraulic power units, stationary hydraulic stations and mobile hydraulic equipment as reservoir breather.
