Negative pressure weighing hood

Product advantages:

Work area integrated arc design, no dead corners, no dust accumulation, easy to clean.

The air curtain is isolated, the personnel and materials are easy to enter and exit, the operation is convenient, and there is no hygienic dead angle.

The patented design of differential pressure balance ensures that the pressure difference in the background area does not change.

The one-way flow pattern is good, the dust does not spread, and the dust capture effect is good.

A cooling unit can be added to ensure that the temperature of the equipment is within the control range during operation.

Combined with the company's testing methods, the filter grade can be reasonably selected.

Weighing equipment control is integrated into the equipment according to customer requirements.

The isolation methods include air curtain isolation, soft curtain isolation, and plexiglass isolation.

The return air orifice is fixed by strong magnet, which is easy to disassemble and assemble.

Technical indicators:

Air velocity is 0.45m/s±20%.

Equipped with control system.

Wind speed sensor, temperature and humidity sensor are optional.

High-efficiency fan modules provide clean laminar air 

(measured with 0.3µm particles) to meet cleanroom requirements with efficiencies up to 99.995%.

Filter module:

Primary filter - plate filter G4;

Medium efficiency filter - bag filter F8;

High-efficiency filter - liquid tank high-efficiency non-partition filter H14.

380V power supply.
