Air Filters

Core Technical Specifications

Solid Particle Filtration Precision: ≥1μm agricultural dust, crop fiber, pollen

Filter Media: High-strength hydrophobic composite filter paper + granular activated carbon interlayer, anti-mold, anti-hydrolysis, resistant to farm humid & dusty working conditions

Standard Replacement Cycle

Mild farming environment: 500 working hours or 6 months

Mandatory Replacement Trigger: Weak cab air outlet airflow, visible dust accumulation on filter surface, obvious odor inside cab

Differential Pressure Thresholds

Initial pressure drop of new element: ≤0.3 kPa

Blockage alarm threshold: ≥1.2 kPa

Structural Construction Features

Full surrounding foam rubber sealing ring, zero air bypass, prevent unfiltered dust entering cab

External metal support mesh avoids filter paper collapse under long-term negative pressure ventilation

Integrated activated carbon interlayer, one filter realizes dust filtration + deodorization two functions

Deep uniform fold design, huge dust storage capacity, extend service interval during continuous farm operations

Key Product Advantages

Dual composite filtration design for farm harsh environment

Blocks field dust, straw chaff and pollen meanwhile eliminates fertilizer, diesel and crop odors, greatly improve operator cab air comfort.

High-strength waterproof filter paper, anti-clogging in humid farmland

Not easy to mildew or block after exposure to field moisture, maintain stable ventilation flow during rainy season farming.

Integrated foam sealing structure, no air leakage

Prevent fine dust bypass entering cab, avoid cab window fogging and instrument panel dust accumulation.

Working Principle

Outside field air mixed with crop dust, pollen and farm odors flows from outside to inside through filter media.

Outer composite filter paper intercepts solid impurities: soil dust, straw fiber, pollen and crop debris.

Middle activated carbon interlayer adsorbs volatile odors, diesel exhaust and fertilizer peculiar smell.

Clean fresh air flows into tractor cab through air conditioner ventilation pipeline.

Filter media cannot be washed or regenerated; once fully covered with dust and carbon saturated, full replacement is required.

Application Scope

Farm ploughing, seeding, harvesting, straw returning, orchard management, large field continuous farming operations.
