I. 30 Cubic Meter Air Purification Chamber

Standards Based On:

GB/18801-2015 Air Purifier

GB/18803-2002 Indoor Air Quality Standard

GB 4706.45 Safety of Household and Similar Electrical Appliances - Particular Requirements for Air Purifiers

The 30m3 large environmental test chamber features a 10mm thick emulsified glass inner wall, with a SUS304# stainless steel frame and specially formulated low-adsorption sealant as the sealing material. The chamber's air purification system is equipped with a multi-functional air filter to remove particulate matter and chemical pollutants such as ammonia. The chamber directly draws air from the office environment for temperature and humidity, which enters the test chamber after passing through the filtration system. The chamber is equipped with a temperature and humidity monitoring system, allowing real-time observation of temperature and humidity conditions.

II. 20 Cubic Meter Environmental Disinfection Evaluation Chamber

Standards Based On:

GB/T38504 Evaluation Method for Spray Disinfection Efficacy

GB/18803-2002 Indoor Air Quality Standard

GB/18801-2015 Air Purifier Standard

GB/T18883-2002 Indoor Air Quality Standard

The environmental disinfection evaluation chamber consists of an environmental test chamber and a sterilization filtration system, used to verify the disinfection efficacy of disinfectants and disinfection equipment after spray application in the air; it is widely applicable for simulating and testing the pollutant removal performance of air purifiers. The chamber is designed and manufactured in accordance with 《GB/T 18801-2015 Air Purifier》. The principle and structure are configured according to Appendix D of GB/T 38504 Evaluation Method for Spray Disinfection Efficacy.

III. 1 Cubic Meter Coating Material Formaldehyde Purification Performance Test Chamber

Standards Based On:

JC/T 1074-2021 《Purification Performance of Coating Materials for Indoor Air Purification Function》

The coating material purification performance test chamber is a set of specialized test chambers developed according to the JC/T1074-2021 standard for testing the purification performance of air purification products. This product provides a test environment that meets standard requirements with good airtightness and low adsorption and release of pollutants from the chamber surface. Under specified test conditions, it evaluates the sustained purification capacity of indoor air purification functional coating materials for target pollutants after applying a specified concentration multiple times over a defined period (or time).
