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. GCV 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	GCV (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. Binder-free construction is easy to overlook on a pre-filter, yet it matters most there: if the upstream stage contains organic adhesive, its outgassing and flaked debris are carried straight into the downstream main HEPA and the process itself — a contamination source placed immediately ahead of the cleanest point in the system. GCV shares the all-inorganic construction of ATMCU/ATMV, so there is no organic break anywhere along the airflow path.
