NIPPON MUKI 전용관
GCW 무바인더 저발진 500°C 내열 Semi-HEPA 필터
제품 개요
GCW는 500°C에서 연속 사용하는 내열 Semi-HEPA 필터로 효율은 0.5-1.0 μm 기준 90%입니다. 유리섬유 여재에 스테인리스 강망 보강을 더하여 고온 HEPA(ATMWC)의 전단 필터로 쓰기에 알맞고, 요구 수준은 낮지만 여전히 높은 효율이 필요한 고온 여과 현장에도 적합합니다.
주요 특징
・500°C 연속 사용
・효율 90% @ 0.5-1.0 μm(Semi-HEPA)
・고강도 사양(유리섬유+스테인리스 강망)
・ATMWC 전단 필터로 써서 주 필터 수명을 연장
・무바인더 구조: 여재와 실링 모두 유기 접착제를 쓰지 않아 저발진, 실록산 방출 없음

상세 설명
GCW provides upstream protection for ATMWC HEPA filters, capturing larger particulates to extend the life of the more expensive main filter. All-inorganic construction maintains full-system temperature rating.

Airflow vs Pressure Drop (representative)
Binder-Free, Low-Shedding Construction
A conventional HEPA bonds and seals its media and frame with polyurethane (PU) or silicone, and those sealants are generally rated for long-term service somewhere in the 100–200°C range. Above that, the adhesive first softens and cracks, releasing organic molecules, then embrittles and flakes under repeated thermal cycling — at which point the filter itself becomes a particle source. GCW uses no organic adhesive anywhere: sealing is done with glass fiber, the frame and separators are stainless steel, and the entire assembly is metal and glass only.| Component | Conventional adhesive HEPA | GCW (binder-free) |
|---|---|---|
| Sealant | Polyurethane / silicone | GLASS FIBER |
| Media bonding | Organic binder | None (glass fiber held by wire net) |
| Separator | Aluminium foil + hot-melt | STAINLESS STEEL |
| Outgassing at temperature | Organic molecules, siloxane | None |
| Shedding after thermal cycling | Rises as adhesive degrades | Stays stable |
With no organic adhesive there is nothing to thermally decompose. Two practical consequences follow:
- Low particle shedding — degrading, flaking adhesive is the most common source of self-generated particles in high-temperature filters. A binder-free build keeps downstream particle counts from creeping back up as the filter ages through repeated heat-up and cool-down cycles.
- No siloxane contamination — silicone seals release siloxane at elevated temperature, and siloxane deposited on wafers, optical surfaces or coated substrates causes hazing and yield loss. Semiconductor, optical coating and OLED processes are particularly sensitive to this.
GCW normally sits upstream of ATMWC, and both stages have to be all-inorganic for the assembly to genuinely hold 500°C. If the upstream stage uses organic adhesive it decomposes first, feeding debris and outgassing straight into the downstream main HEPA — which effectively pulls the whole system's temperature ceiling back down to whatever that adhesive can take.
