Key Product Features
1. High-Power Cummins Diesel Engine, Low Fuel Consumption
Powered by an authentic Cummins diesel engine, the compressor realizes full-range optimal fuel combustion. It features strong power output, ultra-high operational reliability, and excellent fuel economy, effectively reducing long-term fuel costs for field operations and avoiding insufficient power in high-intensity drilling and construction work.
2. Ultra-Efficient All-Weather Cooling System
Developed with core R&D technologies from Kaishan’s North American R&D Center, the independent cooling system adopts separate oil, water, and air coolers matched with a large-diameter high-efficiency fan. It solves the pain points of high-temperature overheating shutdowns in summer and poor cooling effect in cold weather, keeping the compressor in optimal working condition in extreme high and low-temperature environments.
3. Optional Low-Temperature & High-Altitude Startup System
Equipped with a professional fuel heater and circulating heat exchanger, the system autonomously heats coolant and lubricating oil. It enables reliable instant startup in severe cold, high-altitude, and low-pressure environments, completely solving the problem of difficult startup or failure to start for field equipment in plateau and winter low-temperature scenarios.
4. Low Maintenance Cost & Easy Daily Servicing
The fully enclosed chassis and soundproof canopy design effectively reduce operating noise and improve on-site environmental compliance. The reserved wide-opening maintenance doors allow quick access to core components including air filters, oil filters, and separator cores. It greatly shortens equipment maintenance time, reduces downtime loss, and cuts daily after-sales maintenance costs for users.
5. Special Anti-Coking Industrial Lubricant
Matched with exclusive customized compressor lubricant, the product boasts stable viscosity and excellent chemical adaptability under ultra-high and ultra-low temperatures. It prevents oil coking, pipeline blockage, and component wear during long-term high-load operation, ensuring long-term stable service life of the equipment.
Industry Applications
Stable and sufficient compressed air is the core guarantee for smooth drilling and construction operations. During mechanical drilling, a large amount of heat and dust will be generated; insufficient air supply will lead to drill bit damage, dust blockage, and even sudden equipment failure, seriously delaying the construction progress.
The LGZJ-36/30-41/20K Kaishan mobile screw air compressor provides constant-pressure, high-flow stable air source, perfectly adapting to deep well drilling working conditions. It is widely applicable to highway and railway construction, open-pit mining, water conservancy projects, shipbuilding, urban infrastructure, new energy engineering, military industry, and other heavy industrial fields, serving as a reliable air supply equipment for global engineering projects.
