Description

Negative Pressure Weighing Booth

Negative pressure weighing booth for powder feeding, sampling & weighing, stable micro negative pressure with Class 100 vertical laminar flow, 3-stage filtration up to 99.995% @0.3μm, SUS304 standard, 316L optional for corrosive environment. Protect operators from toxic active powder, avoid cross contamination, custom size & air volume for pharmaceutical, biotech and fine chemical clean projects.

Product Overview

Our negative pressure weighing booth is a local purification equipment specially used for powder feeding, weighing and sampling. It maintains stable micro negative pressure inside with Class 100 vertical laminar airflow.

The powder and medicinal dust generated during operation are captured inward without leakage, which can not only protect operators from damage of toxic and active materials, but also avoid material cross-contamination and pollution to the whole workshop environment.

The whole machine is standard equipped with SUS304 stainless steel, and SUS316L stainless steel is optional for high-corrosion working conditions. All dimensions, air volume and protection grades support non-standard customization, widely matched with global pharmaceutical, biological laboratory and fine chemical purification projects.

Key Advantages

1. Negative Pressure Dust Locking, Zero Dust Leakage
Sustained stable negative pressure airflow captures all powder dust inside the booth, completely prevent toxic active powder from escaping into workshop air, fully meet OEB high containment protection requirements.

2. Three-Stage High-Efficiency Filtration, Grade A Clean Operation Zone
Adopt primary + medium + H14 HEPA three-stage progressive filtration, the filtration efficiency for 0.3μm particles reaches 99.995%, forming stable Grade A clean environment inside the operation area.

3. Sanitary Seamless Arc Stainless Steel Inner Chamber
Integrated seamless arc stainless steel inner cavity without hidden dust dead corners, can withstand repeated alcohol, hydrogen peroxide wiping and VHP fumigation, fully comply with GMP hygiene standards.

4. Intelligent Real-Time Monitoring & Optional Functions
Equipped with touch control screen to display differential pressure and wind speed in real time; UV sterilization lamp and variable frequency fan speed regulation can be selected according to project demands.

5. Two Material Options For Different Working Conditions
SUS304 stainless steel for general pharmaceutical clean rooms; SUS316L stainless steel for acid, alkali and high-corrosion fine chemical projects.

6. Full Non-Standard Customization For Different Process Layout
Support customized booth size, internal operation width, air volume and protection grade to match different weighing, feeding and sampling process stations.

Application Scenarios

Pharmaceutical high active API weighing, sampling and feeding workshop
Biological laboratory toxic powder testing & preparation room
Fine chemical raw material powder purification operating area
New material nano powder constant temperature weighing room
Medical intermediate raw material sterile sampling clean area
Cosmetic high-concentration powder batching clean station
