Product Overview

This document provides technical specifications and features of the DUO-60 and DUO-80 air pumps/compressors, designed primarily for applications such as septic tanks (biological contact aeration) and air injection for bubble baths. These units are suitable for small to medium capacity air pumping needs.

Key Features

• Rated pressure suitable for both 50Hz and 60Hz power frequencies.
• Easy restart functionality via a micro switch.
• Two-directional control valve for operational flexibility.
• No grounding required, enhancing installation convenience.
• Designed for outdoor use with rainproof construction.

Technical Specifications

Dimensions

The units have compact dimensions with key measurements including a diameter of 18 mm and various lengths and heights specified in millimeters (e.g., 190 mm length, 126 mm height). These dimensions support easy installation in various settings.

Performance Curves

Performance graphs indicate airflow volume versus pressure for both models, showing operational ranges and efficiency at different pressures. The DUO-60 operates effectively within 5 to 23.5 kPa, while the DUO-80 covers a slightly wider pressure range up to 27.5 kPa.

Applications and Recommendations

These air pumps are recommended for use in septic tanks requiring biological contact aeration and for air injection systems such as bubble baths. Their rainproof design and no-grounding requirement make them suitable for outdoor installations. The easy restart feature and two-directional valve enhance operational reliability and flexibility.
