VACUUM PUMP - 1.5 CFM SINGLE STAGE

As a specialized enterprise in making vacuum pumps, we are always devoting ourselves to
satisfying users’ need of high-qualified products. We adopt the latest design and technique to
make sure that our products use less energy, produce less noise and last long, but also are the
best design for protecting the environment and emitting less pollution. Our excellent design
and manufacturing will bring you more convenience.

1. Pump Use

ATD vacuum pumps are designed to obtain vacuum by pumping gas from sealed containers.

They are suitable for use with R12, R22 and R134a air conditioning systems, as well as
medical appliances, printing machinery and vacuum packing. They can be continuously used

°F (-5°C) to 140°F (60°C).

2. Features

Oil Anti-flow back Design

The gas inlet is specially designed to prevent the oil from flowing back, preventing the
container being pumped as well as the hoses from becoming contaminated.

Environmental Design

The tank has separating devices at the exhaust port to prevent oil spraying and to reduce
pollution.

Aluminum Alloy Casing

The ATD vacuum pump is man ufactured with an aluminum alloy casing.
Because aluminum has good heat dissipation qualities, it will help to keep the pump running
more efficiently for a longer period of time.

Overall Design

The electric components and the pump are designed to make the product compact and lighter.

Easy to start, Faster to pump

The starter design makes the ATD vacuum pump easy to start even in lower temperatures.
This feature allows higher efficiency and faster pumping.

Low Noise and Vibration

An electrometric-coupling insert between the motor and module results in extremely quiet and
smooth operation.
