Liugong SP270255 Air Conditioner Fresh Air Filter: Fresh air enters the cabin cleanly, protecting both people and the machine.

During construction machinery operations, the cab's... “ Fresh air supply ” Entirely reliant on the air-conditioning and fresh-air system, whereas... SP270255 The air conditioner’s fresh-air filter is this very supply line. “ First sentry post ” During outdoor operations, sand and dust kicked up, carbon particles from exhaust gases, and irritating vapors released by materials—when not filtered and allowed to enter the cab directly via fresh air—can not only irritate the driver’s nasal and oral mucous membranes, causing coughing and dizziness, but also travel with the airflow into the air-conditioning evaporator, ducts, and fan, leading to dust accumulation and blockage of the fins, wear on the fan bearings, slower cooling performance, significantly increased noise levels, and even system failures. LiuGong. SP270255 Air conditioning fresh-air filter, custom-made by the original manufacturer. “ Fresh Air Purification Gate ” , to “ Blocks dirt but not wind. ” Its core advantage ensures clean, fresh air enters the cabin with peace of mind, while also establishing a robust protective barrier for the air conditioning system.

Factory-exclusive compatibility: Tight seal at the fresh-air inlet—no leakage or contamination possible.

The sealing performance of the fresh-air filter directly determines the purification effect, LiuGong. SP270255 Development of a new air intake structure for air conditioners that is fully aligned with specific model specifications: The dimensional tolerance between the filter frame and the fresh-air access port is controlled within... 0.3mm Inside, it can be precisely fitted without any trimming required. The edges are sealed with a flexible foam gasket custom-made by the manufacturer; when compressed, this gasket tightly fills even the tiniest gaps between the filter and the hatch, completely eliminating the use of non-genuine filters. “ The loose border causes air leakage on the sides. ” the issue —— Even the diameter 0.5 μm Even the finest dust particles cannot bypass the filter through the gaps; the angle of the installation clip perfectly matches the fixing groove inside the fresh-air compartment, allowing the driver to secure it simply by pressing down with their bare hands. The entire replacement process takes no more than... 2 Minutes—easily completed during construction breaks. “ New Wind Post ” Upgrade.

Graded targeted filtration: First block large particles, then remove microcontaminants.

For outdoor work “ Large particles in abundance, with diverse pollutants. ” the characteristics of, SP270255 Adopt “ Double-layer gradient filtration ” Structure, implementation “ First block the impact, then refine purification. ” The outer layer is a coarse filter made of wear-resistant polyester fiber, with an optimally adjusted fiber density that efficiently traps particles with diameters greater than... 10 μm sand and gravel particles, and debris from dead leaves—its interception efficiency reaches 99% Avoid letting hard objects enter the interior of the air conditioner and scratch the evaporator fins. The inner layer is an electrostatically charged meltblown filter layer that utilizes the principle of electrostatic adsorption to... 0.3–10 μm of the PM2.5 The capture rate for fine pollutants such as exhaust carbon particles and pollen reaches... 92% Furthermore, this design can also filter out some bacterial spores attached to dust particles, thereby reducing the risk of respiratory infections. Such a design not only protects the inner fine-filter material but also ensures that the purification effect is more focused on targeting the core pollutants.

Low-resistance fresh-air design: Purifies without feeling stuffy, making air conditioning more efficient.

If the fresh-air filter has excessive airflow resistance, it can lead to insufficient fresh air volume in the cab, causing stuffiness and oxygen deficiency. LiuGong. SP270255 Resolve this contradiction through dual-structure optimization: The filter material adopts... “ Wavy pleated design ” In the same installation space, the filtration area is larger than that of a flat filter screen. 60% This not only enhances the dust-holding capacity but also reduces airflow resistance per unit area. The fiber pores in the meltblown layer have been optimized through airflow simulation, forming... “ Maze-style ventilation channel ” The resistance to airflow is reduced compared to conventional filters. 18% Actual measurements show that installation... SP270255 Afterward, the air intake volume of the air conditioner’s fresh-air mode only decreases slightly. 5% , significantly lower than the industry average 15% the average decay rate, ensuring that the cab is constantly supplied with ample, clean, fresh air while also preventing the air conditioning fan from... “ Hold your breath ” Overload operation.

Durable and upgraded: weather-resistant and dust-proof, reducing replacement hassle.

The fresh-air filter is exposed to harsh outdoor conditions for extended periods. SP270255 Enhanced for durability: The frame is made with age-resistant materials. ABS Engineering plastics, after -30℃ To 85℃ The high- and low-temperature cycling test shows no brittle cracking or deformation, enabling the product to withstand both the severe cold of northern regions and the scorching heat of southern regions. The filter material surface is treated with an anti-sticking coating, preventing dust from clumping once it adheres; in cases of minor contamination, simply using compressed air to blow backwards can restore some of its original filtration capacity. The sealing strips are made of EPDM rubber, which is resistant to ozone and oil contamination—ensuring that they won't harden or crack even after prolonged exposure to exhaust gases, thus maintaining long-term sealing performance. In high-dust environments such as mines, its effective service life can be several times longer than that of conventional fresh-air filters. 1.2 Moreover, it significantly reduces the frequency of replacements and operational maintenance costs.

End-to-end quality control: Original manufacturer standards, with traceable purification performance.

LiuGong vs. SP270255 Execute “ From fiber to finished product ” End-to-end quality control: Filter materials must pass... 800 Hourly dust-loading tests are conducted to verify the dust-holding capacity and the degradation of filtration efficiency. Each batch of filters is sampled for airtightness testing (simulating no air leakage under fresh-air pressure) and airflow resistance testing (ensuring compliance with HVAC system specifications). At the finished-product stage, impact resistance tests are also performed (simulating impacts from flying sand and gravel without causing any damage). Each filter is equipped with a unique, factory-originated traceability code; scanning this code allows users to access the production batch information and inspection reports, completely eliminating counterfeit products. “ Filter invalid ” Hidden risks that allow users to use it with peace of mind.

Choose Liugong SP270255 The air conditioning fresh-air filter isn't just a simple replacement part—it's designed for the cab. “ Fresh air inlet ” Install a reliable one. “ Purification gate ” It not only blocks outdoor pollution to protect the driver’s health, but also reduces dust accumulation and wear in the air-conditioning system, thereby extending the equipment’s lifespan. Moreover, its low-resistance design ensures a steady supply of fresh air, allowing drivers to breathe clean, fresh air even in hot construction sites or dusty mines. When your equipment needs a new fresh-air filter, SP270255 will be “ Guardian + Protect the device ” The optimal solution for dual demands builds an invisible health defense line for construction machinery operations.
