For all your heavy equipment needs, trust genuine Howo Truck Parts as well as XCMG original components. It is a critical component for maintaining engine performance, reducing wear, and extending service intervals on GR series graders.
The 803190351 Lockable Air Filter is manufactured to ISO 5011 standards, with a filtration efficiency of 99.9% at 5 microns and a dust holding capacity of 1500 grams. The assembly includes a primary filter element with a radial seal and a secondary safety element for backup protection. The housing is made from impact-resistant polypropylene with a UV-stabilized black finish. As a genuine XCMG part, it matches the original mounting bracket, intake tube diameter, and latch locations exactly.
Engineered for extreme durability, the 803190351 Lockable Air Filter has an operating temperature range of -40°C to +85°C and is resistant to dust, water, and vibration. The lockable lid features a stainless steel latch and a padlock eye for security. Each assembly is 100% tested for seal integrity and pressure drop. Using genuine XCMG air filters prevents dust ingestion, turbocharger damage, and premature engine wear, ensuring reliable performance in the harshest grading environments.

Genuine XCMG lockable air filter is essential for maximizing engine life in dusty environments. Its robust construction, high-efficiency media, and security features make it the preferred choice for fleet operators who demand reliability and protection against contamination.
Aftermarket air filters often use lower-grade media that allows fine dust to pass through, leading to accelerated engine wear. The genuine 803190351 Lockable Air Filter from XCMG features a multi-layer synthetic media with a high dust-holding capacity. Independent tests show that OEM filters maintain 99.9% efficiency for 1,000 hours of operation, while generic filters may drop to 95% after 500 hours. This reliability prevents cylinder scoring, ring wear, and turbocharger damage.
Each 803190351 Lockable Air Filter is traceable to its production batch, with records of media batch, burst strength, and efficiency testing. The housing is molded with the XCMG part number and date code for easy identification. XCMG’s quality control includes 100% leak testing of the housing seal and random sampling for ISO 5011 efficiency validation. Only filters that meet all specifications are shipped, ensuring reliable protection for your grader’s engine.
Installing the 803190351 Lockable Air Filter requires the engine to be off. Unlock the lid latches and remove the cover. Clean the inside of the housing with a damp cloth. Insert the primary filter element, ensuring the radial seal seats correctly. Install the safety element (if removed). Close the lid and secure the latches. Lock the padlock eye if desired. Reset the restriction gauge after installation.
Inspect the 803190351 Lockable Air Filter every 250 hours using the restriction gauge. Replace the primary element when the gauge reaches the red zone or every 500 hours. Never blow out the element with compressed air, as this can damage the media. When replacing, also inspect the safety element (replace every second primary change). Store spare elements in a clean, dry place. Keep a spare primary element in your parts inventory, as a clogged filter reduces power and increases fuel consumption.
A dirty or damaged air filter allows dust to enter the engine, causing abrasive wear on cylinders, rings, and bearings. The genuine 803190351 Lockable Air Filter restores proper filtration, keeping the intake air clean and reducing engine wear by up to 80%. Operators report lower oil consumption, less blow-by, and longer engine life after switching to OEM filters. The lockable lid also prevents tampering and ensures the filter element is always properly seated.
In a fleet study of 20 XCMG GR215 graders, those using genuine 803190351 Lockable Air Filters had 75% fewer engine dusting incidents over 6,000 hours compared to machines with aftermarket filters. The improved filtration also extended turbocharger life by 50%. For contractors who operate in dusty conditions, an OEM lockable air filter is a critical investment.
XCMG’s filter plant uses automated pleating machines to ensure consistent media spacing and bonding. The 803190351 Lockable Air Filter media is pleated to maximize surface area while maintaining low restriction. The housing is injection-molded from glass-filled polypropylene for high strength. The lid latch is assembled with stainless steel springs and tested for 10,000 open-close cycles. Each filter assembly is 100% leak-tested and validated for efficiency on an ISO 5011 test stand.
All 803190351 Lockable Air Filters are individually boxed with a restriction gauge and installation guide. Bulk orders of 5 or more are shipped in reinforced cartons. XCMG’s global distribution network ensures fast delivery to any location. For fleet operators, filter exchange programs are available to minimize inventory costs. Technical support for correct installation is available via the contact buttons above.
The 803190351 Lockable Air Filter directly replaces original part numbers 803190350 and 803190352. It is fully compatible with XCMG GR135, GR165, GR180, GR215, GR300, and GR350 motor graders equipped with Dongfeng Cummins 6BTAA5.9 engines. This assembly also fits the air intake system on many XCMG wheel loaders. For engines with a larger air flow requirement, use part 803190353. Always verify your engine model and intake tube diameter before ordering.
When replacing the air filter, also order a new primary element (part 803190354) and safety element (803190355). XCMG recommends replacing the filter housing every 10,000 hours or if the locking latch becomes loose. Keep one spare 803190351 Lockable Air Filter in your parts warehouse for emergency replacement. For fleet operators, bulk orders of 10 or more include a 10% discount and free shipping.
For custom inlet/outlet configurations or high-humidity environments, use the buttons above to contact our technical sales team. We can also supply filter assemblies with pre-cleaners for extreme dust conditions. Always provide your grader’s serial number and a photo of the existing filter when ordering the 803190351 Lockable Air Filter to ensure perfect fitment.
