The Dust-Free Clean Oven is designed for high-precision applications in industries such as electronics, liquid crystal displays (LCD), CMOS, IS, pharmaceuticals, and laboratories. It is ideal for drying, heat treatment, and aging processes of non-volatile and non-flammable materials under controlled high-temperature conditions.
Key Features:
1. This oven ensures a Class 100 clean environment, suitable for normal operating conditions to maintain high cleanliness standards.
2. Constructed with full argon welding and high-temperature resistant silicone seals, the oven uses SUS304# stainless steel heating elements and anti-dust tables to minimize particle generation.
3. The inner chamber is made of imported 800-inch mirror-finish SUS304# stainless steel plates, cleaned with alkaline soda water to remove oils and prevent contamination during baking.
4. Equipped with a 24" x 24" x 5-7/8" HEPA filter system, it provides 99.99% filtration efficiency, maintaining a Class 100 environment. An automatic damper controls the 3" φ exhaust port for efficient air exchange.
Standards Compliance:
- GB/T11158-1989: High-temperature test box technical specifications

Difference Between Class 100 and Class 1000 Ovens:
While both ovens offer high cleanliness, the Class 100 model includes a dedicated air purification system, whereas the Class 1000 model has a less stringent system. If your application doesn't require an air purification system, a standard nitrogen-filled oven may be sufficient.
Shanghai Huanqi Test Equipment Factory recommends selecting the appropriate model based on your specific needs and environmental requirements.
