The SDP900E portable screw air compressor is designed to meet high-demand applications and perform reliably under extreme field conditions. It features low fuel consumption, significantly reducing operational costs. The oil tank is installed in a submersed structure, placed around each unit, increasing oil capacity and extending oiling intervals. This design also ensures balanced weight distribution on both sides. By placing the oil tank outside the main casing, more internal space is available, which makes maintenance easier and reduces noise levels. This enhances the overall user experience and provides excellent value for money. Key Advantages:
1. **High Reliability** – Fewer compressor parts and no wearing components ensure long service life with overhaul intervals up to 40,000 to 80,000 hours.
2. **Easy Operation and Maintenance** – High automation allows for unattended operation without requiring extensive training.
3. **Good Power Balance** – No unbalanced inertia forces allow smooth high-speed operation, making it ideal for portable compressors with compact size, light weight, and small footprint.
4. **Strong Adaptability** – With forced gas transmission characteristics, it maintains high efficiency across a wide speed range, regardless of exhaust pressure. Our SDP Series:

Product Accessories:
1. **Brand Screw Host** – Large rotors, low RPM, long lifespan, high efficiency, low noise, low vibration, high reliability. Bearings last over 100,000 hours. Low power-to-airflow ratio and minimal wear parts mean low maintenance cost.
2. **Motor** – High-efficiency air-cooled, totally enclosed motor with large starting torque, low noise, and IP55 protection. Features imported SKF bearings and F-grade insulation.
3. **Intake Valve Assembly** – Non-load starting with butterfly inlet control valve. Offers 0–100% stepless volume regulation, aluminum alloy casing, and non-return valves for heavy load and emergency stop scenarios.
4. **Air Filter** – From Mann Hummel Germany, removes 99.9% of dust with a filtration fineness of 3 μm. Ensures clean air intake and extends system lifespan by over 3,000 hours.
5. **Oil System** – Oil filter from Mann Hummel Germany. Removes dust from oil with a fineness of less than 0.1 μm. Provides good lubrication and cooling. Application Fields:
