Detailed Description

ATMV/ATMVC adds stainless-steel mesh reinforcement on top of the ATMCU platform. Choose this strengthened version when the application involves mechanical vibration or high face velocity — for example, downstream of blower units in nuclear ventilation systems.

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. ATMV/ATMVC 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	ATMV/ATMVC (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. ATMV/ATMVC is typically installed where vibration is present — downstream of blowers, or in high-velocity ducting. Vibration accelerates fatigue and flaking of any adhesive layer, so shedding shows up earlier than in static installations. That is precisely why binder-free matters more on the reinforced models: the wire-net reinforcement handles mechanical strength while the binder-free build handles cleanliness, with neither traded off against the other.

Applications

- HEPA downstream of nuclear ventilation blowers - Terminal filtration on vibrating high-temperature equipment - Power-plant high-temperature high-velocity airflow

Selection Notes

- For static depyrogenation tunnels, ATMCU is more economical. - For vibrating or high-velocity applications, choose ATMV/ATMVC. - **150 mm (Q) / 290 mm (P)** — select by airflow demand.
