Core Definition
Quick-clamp high-temperature filter cartridges fasten the filter end cap to the equipment port via stainless steel quick-clamp ferrite with a built-in handle, enabling rapid locking or opening without tools. Featuring fast disassembly & assembly and reliable sealing, this connection type delivers extremely high maintenance efficiency under high-temperature conditions, and is widely applied to custom high-temperature SLM equipment, powder processing systems and scenarios requiring rapid cartridge replacement.
This product adopts high-temperature resistant glass fiber or ceramic fiber filter media matched with high-temperature resistant sealing gaskets, with an operating temperature range of 150–260℃. It meets H13 filtration grade per EN 1822 standard. The quick-clamp joint remains easy to mount and dismount at high temperatures, greatly cutting downtime for maintenance of high-temperature equipment.
Core Technical Advantages
Rapid mounting & dismounting via quick-clamp ferrite: The stainless steel quick-clamp ferrite comes with a handle for manual locking and unlocking without any tools. Even under high-temperature working conditions, single disassembly/assembly time can be reduced to 10–20 seconds.
High-temperature resistant sealing system: End cap sealing adopts high-temperature graphite gaskets (up to 500℃) or flexible graphite spiral wound gaskets. Combined with the clamping force of the quick ferrite, stable sealing performance is maintained at high temperatures.
High-temperature resistant filter media system: Available with high-temperature glass fiber (200℃) or ceramic fiber (260℃) media supported by stainless steel frames; PTFE membrane coating is optional.
Excellent interchangeability of standard joints: The quick-clamp joint complies with ISO standards, allowing cross-brand interchange under high-temperature conditions and convenient spare parts management.
Stainless steel mesh protective layer: A stainless steel grid is fitted on the outer layer of the cartridge to protect filter media from mechanical damage at high temperatures and assist static electricity dissipation.

Case & Data Verification
Case: Application of Quick-Clamp High-Temperature Filter Cartridges in a High-Temperature Powder Processing System
A high-temperature powder recovery system handles titanium alloy powder at 200℃ and requires regular filter replacement. After adopting quick-clamp high-temperature filter cartridges sealed with graphite gaskets, tool-free locking via stainless steel ferrite cuts replacement time from 30 minutes (bolt-fixed type) to 3 minutes. No leakage occurred with reliable high-temperature sealing after 12 months of continuous operation.
FAQ
Q1: Will the quick-clamp ferrite loosen under high temperatures?
A: Stainless steel quick-clamp ferrite expands moderately at high temperatures. The eccentric handle design compensates for thermal expansion to maintain stable clamping force. It is recommended to check the handle position after temperature rise/fall and re-tighten if necessary.
Q2: How to select high-temperature sealing gaskets for quick-clamp joints?
A: Flexible graphite gaskets for temperatures below 200℃; metal spiral wound graphite gaskets for 200–500℃; all-metal sealing for temperatures above 500℃. Flexible graphite gaskets suffice for general high-temperature working conditions such as aluminum alloy printing.
Q3: How is static electricity conducted to ground via quick-clamp high-temperature filter cartridges?
A: Static electricity flows sequentially through the conductive layer of filter media, stainless steel mesh layer, stainless steel quick-clamp ferrite and equipment ground wire. Ensure good electrical conductivity between the ferrite and equipment, and reliable connection of the ground wire.
Q4: Are quick-clamp high-temperature filter cartridges applicable to EBM equipment?
A: Glass fiber media with graphite gaskets for temperatures below 200℃; ceramic fiber media with metal sealing gaskets and Inconel ferrite for 200–500℃; full Inconel construction required for temperatures above 500℃.
