Products Description

The Heavy-Duty Primary Air Filter Element is designed specifically for heavy-duty industrial equipment operating in dusty environments.
It uses high-performance wood pulp filter paper that can capture a large amount of dust, dirt, and particulate matter from the ambient air. The purified intake can reduce the wear of the main moving parts, slow down the degradation of lubricants, and extend the service life of the secondary filter and downstream components.
This heavy-duty filter element is made of reinforced support structure and high toughness filter material, which can maintain reliable filtration performance even after long-term continuous operation. Even in dusty and harsh workshops, mining areas, and construction sites, it can prevent deformation and maintain low pressure drop. Equipped with double-layer metal mesh to reinforce the filter material, and using sturdy plastic end caps to achieve precision. Widely used in excavators, loaders, generator sets, and heavy machinery in dusty working environments. We can customize production according to customers' OEM part numbers and size requirements.
Products Feature
01
Double protection guarantee
As a safe internal filter, once the main filter element is damaged, it can intercept dust and form a backup protection, greatly reducing the risk of damage to the main engine. It is suitable for high dust and harsh working conditions such as construction sites and mines.
02
Double layer metal mesh support
The inner and outer diamond shaped metal mesh reinforces the filter paper, resisting the impact of airflow and preventing the filter material from collapsing and deforming, resulting in higher strength.
03
Positioning plastic end cap
The top buckle structure ensures precise installation and positioning, ensuring a tight seal and preventing dust from being sucked in by the side; Plastic end caps are resistant to vibration and not easily cracked.
04
Breathable balance, stable resistance
Reasonable wrinkle design, maintaining sufficient intake volume, will not cause excessive intake resistance or decreased power.

faq
Q1: What is the function of Heavy-Duty Primary Air Filter Element?
A1: It is the primary intake filter for heavy-load equipment. It captures large amounts of dust and coarse particles, protects the main unit and reduces the burden of secondary filters.
Q2: What problems will a clogged primary air filter cause?
A2: Blockage increases intake resistance, raises fuel or power consumption, and insufficient air intake will accelerate wear of equipment internal components.
Q3: What working environments suit this heavy-duty air filter?
A3: It is suitable for cement factories, mining sites, construction sites and other environments with high dust concentration.
Q4: Do you support customized heavy-duty primary air filter elements?
A4: Absolutely. We accept custom production according to outer diameter, height and special size requirements.
