Sala de pesaje de presión negativa

1. Introduction

In the process of dust and reagents weighing and packing in the equipment, dust and reagents can be controlled to spill and rise, to prevent dust and reagents from causing inhalation harm to human body, but also to avoid dust and reagents cross-contamination, to protect the safety of the outside environment and indoor personnel.

The negative pressure room is composed of working area, return air box, fan box, air outlet box, outer box, by the initial effect filter + medium effect filter + high efficiency filter, variable air volume air unit, PLC control system and sensing system, etc.

Performance characteristics

• The negative pressure room design, material, manufacture, assembly, debugging and so on met the new GMP pharmaceutical production specification requirements;
• Whole body is made of stainless steel after forming, bending, welding, assembling, high flatness, convenient and clean. The electric cabinet can be selected in two ways: internal and external;
• Compact and compact structure, flexible displacement, economic benefits;
• Unique air supply and exhaust system effectively protects the safety of personnel and avoids environmental pollution and cross-infection of products;
• Special air duct design, effectively control the engine noise;
• the wind to flow to polymer film, wind velocity uniformity can be controlled in 5%-10%, the early effect filter, medium efficiency filters, high efficiency filter replace both from the front or top to tear open outfit;
• Negative pressure weighing chamber adopts modular design, convenient in and out of the field assembly and disassembly between weighing;
• It uses soft connection between fan and negative pressure weighing room, negative pressure weighing room will not produce by the operation of the fan noise and vibration;
• Lighting/sterilization: negative pressure weighing according to indoor ground illumination one meter more than 300 lux, sterilization optional sterilization lamp or ozone sterilization lamp;
• Configurable form a complete set of electronic weighing scales;
• Configurable online printers, print log data in real time;
• Can be configured online wind speed detection, temperature and humidity detector;
• Configurable dust particles, planktonic bacteria detection;
• Configurable PVC administered or isolation glass doors;
• Configurable waterproof dustproof industrial plugs, sockets and differential gauge, quantity according to the requirements of customers;
• Configurable stainless steel weighing (placed weighing apparatus);
• Adopts the man-machine interface, PLC system, carried out in accordance with the formula precision weighing;
• Can undertake related products, customized according to customer’s actual demand;
