INVERSYS DPR SERIES

Product catalog summary

Standard Equipment
The INVERSYS DPR Series rotary screw air compressors come equipped with high-quality components such as IP55 electric motors with IE3 efficiency class, IP54 fan motors, and a star-delta motor starter system. These components are selected according to IEC, UL/cUL, and CE standards, ensuring high efficiency and energy savings.

Serviceability
The compressors are designed for easy serviceability with a layout that allows instant access to consumable items. Quick-release protective covers and user-friendly controllers help minimize downtime and reduce maintenance costs.

Electronic Control and Screw Block
The compressors feature durable microprocessor controllers with communication capabilities for smooth operation. The patented screw block is designed for high-capacity air supply with new rotor profiles that reduce air loss and torque requirements.

Air Oil Separator
The air oil separator is a three-stage design that ensures high-performance separation with low oil mist in the outlet air (≤ 3 ppm). It features an immersed type separator for effective separation in a compact volume.

Main Motor and Drive System
The main motor is of IE3 efficiency class with an option for IE4, designed for ambient temperatures up to 50°C. It supports 50/60 Hz and 380/400/230 V configurations, with direct coupling for efficient power transfer.

Cooling System
The cooling system includes a low-speed radial fan and a high-efficiency impeller design suitable for high ambient temperatures. It features an inverter-controlled fan for models above 30 kW, ensuring low sound levels and efficient cooling.

Advantages
The compressors offer low vibration, high cooling capacity, and easy access through service doors. They support multiple-machine control for up to five machines (55 kW and above).

Technical Data
The document provides detailed technical specifications for various models, including pressure, capacity, motor power, connection size, dimensions, weight, and noise levels. Performance is measured under specific conditions, and the company reserves the right to make changes without notice.
