High Airtightness Pumps

High-airtightness pumps are special air pumps designed to meet specific low-leakage requirements, employing a special sealing design and a dedicated low-leakage diaphragm.

The leakage rate is as low as 10⁻⁷ Pa·m³/s (Pascals per second).

Key Factors to Choose a Model

Leakage

Leakage rate is a core indicator for measuring the sealing performance of an air pump. This pump series offers leakage rates far exceeding conventional diaphragm pumps.

Flow Rates

You can refer to the flow-pressure curve to understand the flow-rate at the actual working point of the pump

Power Supply

According to your power supply system, choose 5V/12V/24V DC or optional AC power adapter

Lifetime

According to your application needs and application load, select product versions with different no-load or full-load life
