Although the GD150/175 truck mounted compressors and XW Mech XYC-37-2 dry bulk truck mounted compressors are both truck-mounted air compressors, they are almost completely different. Below, I will provide a detailed comparison of their main functions, working principles, applicable materials, application industries, maintenance cycles, and price ranges. This will help you understand these two best-selling truck air compressors and choose the one most suitable for your business.
What are Truck Mounted Compressors?
A truck mounted compressor is an air compressor that’s integrated into a truck’s chassis or powered by the truck’s engine or PTO system. It allows the vehicle to supply compressed air wherever it’s needed. Instead of relying on stationary compressors, these mobile units turn trucks into fully equipped air power sources for field operations.
Differences Between XW Mech and GD150/175 Truck Mounted Compressors
1. Core Function
The GD150/175 truck mounted compressors are oil-free bulk liquid compressors manufactured by Gardner Denver. They are primarily used for the oil-free discharge of bulk liquids from tank trucks, supporting the rapid and clean transport of low-viscosity liquids.
The XW Mech XYC-37-2 dry bulk truck mounted compressor utilizes oil-free twin-screw
technology and is specifically designed for dry bulk powder tank trucks, suitable for unloading powders, granules, and other materials.
2. Working Principle
GD150/175 truck mounted compressors belongs to the rotary vane truck mounted compressors. They are consisted of a rotor with several sliding vanes, housed eccentrically inside a cylindrical stator. The rotor is directly connected to the truck’s PTO (power take-off) or hydraulic motor. As the rotor turns, the vanes slide outward due to centrifugal force, forming variable-volume chambers between the rotor and the stator wall. The eccentric rotation causes these chambers to decrease in size, compressing the trapped air as the rotor continues turning.The compressed air is then discharged through the outlet port toward the tanker’s air piping system for liquid material unloading.
XW Mech XYC-37-2 dry bulk truck mounted compressor contains two intermeshing helical rotors—a male (drive) and a female (driven) rotor—housed in a precision casing. As the rotors rotate, air gets trapped between the helical lobes and casing. The volume of these pockets gradually decreases as the rotors mesh, compressing the air. When the trapped air reaches the discharge port, it exits under high pressure and continuous flow.
3. Applicable Materials
The Gardner Denber GD150/175 truck mounted compressors are designed for seamless, oil-free discharge of bulk liquids, including food-grade liquids, solvents, acids, alkalis, hot asphalt, resins, etc.
The XW Mech XYC-37-2 dry bulk truck mounted compressors are designed for oil-free discharge of dry bulks, including food and chemicals, such as sugar, salt, wheat, animal feed, carbon powder, cement, talc powder, etc.
4. Application Industries
The GD150/175 truck mounted compressors offers great convenience in many liquid transporting and discharging industries, including food industry, beverage industry, chemical industry, liquid waste collection industry, construction industry, etc. For example, the GD150/175 truck mounted compressors and pumps can collect and deliver your liquids from road tankers in the shortest times. And the food grade GD150/175 truck mounted compressors will help you discharge your liquid food and beverage at optimal rates. Besides, the GD150/175 truck mounted compressors can be configured to work efficiently with a huge range of liquid chemicals. They are ideal for tank trucks, ensuring fast and flexible liquid transfer without compatibility issues.
The XW Mech XYC-37-2 oil-free screw truck mounted compressors improve efficiency and safety in food industry, animal feed industry, chemical industry, construction industry, etc. And they are specially ideal for the cement tanker and flour tanker. For example, the XYC-37-2 oil-free truck mounted compressors can help the flour tanker safely discharge wheat flour, corn flour, soybean flour, starch, milk powder, sugar powder, etc. And they are also commonly used for the cement tanker to efficiently discharge cement powder, fly ash, lime powder, ground slag powder, gypsum powder, calcium carbonate powder, etc.
5. Drive Options
The compact size and shape of the GD150/175 truck mounted compressors make them ideal for installation in the chassis of most vehicles, enabling low-cost direct PTO drive. The through-shaft design also allows for clockwise or counter-clockwise input drive rotation, and the compressors can be mounted in three orientations, providing maximum installation flexibility.
The XW Mech XYC-37-2 screw truck mounted compressor offers super excellent package adaptability. Allowing users to choose the most efficient power source for their specific working environment, the XW Mech screw truck mounted compressor is suitable for a wide range of vehicle and operational setups. It can match to various different drive options, including PTO drive, diesel engine drive, electric motor drive.
6. Air Pressure & Flow
The GD150/175 truck mounted compressors are optimized for liquid unloading. They state an unloading pressure of up to 36 psi (≈2.5 bar) and a peak flow rate of approximately 75 CFM.
The XW Mech XYC-37-2 truck mounted air compressors are optimized for dry powder. They are good solutions for discharging dry bulk materials often requires higher or more continuous large air volumes. Typical models provide a continuous, stable air volume of several hundred to several thousand CFM at 1.5–2.5 bar (≈22–36 psi) . But the specific airflow and pressure depend on the model.
7. High Temperature & Corrosion Resistance
The GD150/175 truck mounted compressors emphasize corrosion-resistant materials, such as stainless steel rotor, anodized aluminum alloy body, Viton seals, etc. Because they sometimes handle acidic, alkaline, or food-grade liquids, preventing coating peeling or contamination. They also have specialized configurations (high-temperature blade design, heat-resistant seals) for high-temperature or chemical media.
The XW Mech XYC-37-2 vehicle truck mounted compressor prioritizes wear resistance and particle resistance over stringent corrosion resistance (unless handling chemical powders). For high-temperature powders or easily agglomerated materials, additional heating or moisture-proof systems may be required, as well as dust filters/pulse blowers or anti-clogging designs.
8. Cooling Method
The GD150/175 truck mounted compressors are lightweight and compact, primarily air-cooled, and suitable for short-duration liquid unloading tasks. The XW Mech XYC-37-2 truck mounted compressors have a larger displacement and heavier load; they deliver continuous high-pressure compressed air through long pipelines to transport powders, generating significant heat and requiring a high-capacity cooling system. The XYC-37-2 truck mounted compressors primarily use air cooling or water cooling systems.
9. Maintenance Period
The vane blades of the GD150/175 truck mounted compressors require periodic replacement, typically every 5,000-10,000 hours. In contrast, the screw blades of the XW Mech XYC-37-2 truck mounted compressors have a very long lifespan and require almost no maintenance. Only after more than 50,000 hours of operation might it be necessary to replace the bearings or synchronizing gear grease.
10. Price Range
According to Made in China and online platforms such as Amazon, the GD150/175 truck mounted compressor price is generally around $6,000. If you added with more additional parts or functions, the price will be higher even up to $8,000.
According to Made-in-China and online shopping platforms such as Alibaba, the price of XW Mech XYC-37-2 truck mounted compressor generally starts at $4,500. But with different configurations, the XYC-37-2 truck mounted compressor prices ranging from $4,500 to $7,500.
Conclusion
In summary, if your industry requires transporting liquids, and vehicle weight control is critical, the GD150/175 truck mounted compressors are an excellent solution. However, please note that you must be willing to replace the vane blades annually. But if your industry requires dry bulk discharging, and high efficiency, low maintenance, and a long lifespan, and are willing to invest in a single unit, then the XW Mech XYC-37-2 truck mounted compressors are a perfect match.
