QUQ Series Hydraulic Air Filter
Product Overview
QUQ Series Hydraulic Air Filter is a critical tank‑mounted FILTER component for industrial hydraulic system and hydraulic‑driven Machine. It is installed on the top of hydraulic oil reservoir, serving as a breather FILTER to filter ambient air entering the tank when oil level fluctuates. It traps dust, debris and moisture, prevents hydraulic oil contamination, and protects hydraulic pumps, valves and other key parts inside the hydraulic system, lowering failure rate of the whole Machine.
This series of FILTER features compact structure and reliable dust‑proof performance. It keeps internal‑external pressure balanced of the oil tank, avoids vacuum negative‑pressure damage to hydraulic components while the Machine is working. Multiple standard models are available to match different oil‑tank volumes of various hydraulic system.

Working Principle
During operation of the Machine, oil level inside the hydraulic tank rises and falls following the working cycle of the hydraulic system. When oil level drops, outside air flows into the reservoir through the QUQ air FILTER. The filter element intercepts dust and solid impurities in the incoming air, preventing contaminants from mixing into hydraulic oil. When oil level rises, excess internal air is exhausted out through the breather.
The FILTER maintains tank pressure balance, avoids vacuum suction that may damage hydraulic pump of the hydraulic system. The inner filter element is consumable. Users can replace only the filter element instead of the entire FILTER, which keeps filtration performance of the hydraulic system and reduces maintenance cost of the Machine.
Core Advantages
1. Efficient filtering performance of the FILTER, blocks dust and impurities, maintains oil cleanliness, safeguards the hydraulic system and host Machine.
2. Compact and robust structure, suitable for different‑size hydraulic tanks in diverse hydraulic system.
3. Excellent air permeability, ensures smooth air exchange, prevents negative‑pressure risk inside oil tank when the Machine runs.
4. Simple assembly, convenient filter‑element replacement, shortens downtime of the Machine.
5. Widely compatible, fits for new assembly or retrofit of hydraulic system, popular for hydraulic equipment manufacturing and maintenance.
Application Range
QUQ Series Hydraulic Air Filter is widely applied to the hydraulic system of hydraulic power packs, injection molding machines, hydraulic presses, machine tools and other hydraulic‑driven Machine. It is well‑received by hydraulic system manufacturers, maintenance workshops and global spare‑parts distributors.
