Core Value
Caterpillar 131-8822 air filter is the core protective component of heavy-duty equipment engines. In extreme working conditions such as mines and construction sites with high dust concentration, ordinary filter cartridges fail after about 250 hours. However, the original 131-8822 has a tested service life of 500 hours through its unique gradient filtration technology, providing all-weather protection for the equipment.
[Technological Breakthrough]
1. Five layer composite filtration structure
Outer pre filter cotton intercepts large particles such as leaves and flying fluff (>20 microns)
Adsorption of 10-20 μ m dust by double electrostatic fiber layer
Nano resin based paper captures particles>5 microns (compliant with ISO 5011 standard)
Waterproof and oil repellent coating prevents moisture and clumping
Stainless steel support mesh can withstand a burst pressure of 80kPa
2. Sealing performance revolution
Using low-temperature elastic polyurethane sealing rings, it maintains complete sealing performance even in extremely cold environments of -40 ℃ and high temperatures of 120 ℃. After 50000 pulse pressure tests (exceeding industry standards by 30%), unfiltered air bypass is eliminated to prevent early engine wear.
[Compatible models]
Suitable for Caterpillar 300+heavy equipment, including:
Large excavator: 336D2 XE, 340F UHD, 349D
Mining trucks: 777D, 785C, 793F
Bulldozer: D6T XW, D8T, D9T
(Note: Specific compatibility needs to be verified by checking the device SN code, incorrect installation can lead to insufficient air intake)
【 Authenticity Identification Guide 】
The three major features of authentic products:
Filter paper folding depth ≥ 45mm (imitation usually<40mm)
The hot melt adhesive line has a continuous wavy pattern (the imitation is a dotted adhesive)
The anti-counterfeiting code on the outer box can be verified on the official website (the counterfeit QR code is invalid)
[Key Maintenance Data]
Replacement cycle:
• High dust environment: 250 working hours
• Normal working conditions: 500 working hours
Installation specifications:
The filter cartridge compartment must be cleaned before installation
Do not apply engine oil to the sealing ring
The torque of the cover plate bolt is 25 ± 2N · m
Comparison with original factory performance
Third party laboratory testing shows (ISO 12103-1 A4 dust):
Filtration efficiency: Original factory 99.5% vs secondary factory average 93.2%
Dust holding capacity: original factory 1200g vs subsidiary factory 500g
Humidity impact: Under 95% humidity conditions, the original factory efficiency attenuation is less than 3%, while the secondary factory efficiency attenuation is greater than 15%
Actual case: The use of auxiliary filter cartridges in Inner Mongolia coal mines resulted in abnormal wear of Cat C18 engine cylinder liners, with repair costs 17 times higher than the price difference of the original filter cartridges.
User Value
Economy: Reduce fuel consumption by 11% (tested by Carter Laboratory)
Reliability: Extend engine overhaul cycle to 12000 hours
Environmental friendliness: Helping equipment meet emission standards
Carter's 2024 Sahara Desert test shows that the 789D mining truck equipped with 131-8822 can operate continuously for 15000 hours without the need for intermediate repairs.
