Introducción del producto

This three-stage architecture addresses two different contaminant classes in one coordinated housing train. A prefilter protects the downstream components, a HEGA carbon adsorber treats the selected gas load, and a final HEPA removes fine particles. Published containment configurations include three-high by two-wide arrangements with 2, 4 or 6 in prefilters and 11.5, 16 or 18 in primary-filter depths. Each stage must be selected and monitored independently because molecular exhaustion and particle loading do not follow the same signal.

Características clave

Particle and gas control

The HEGA stage adds contaminant-specific adsorption between the protective prefilter and final HEPA.

Containment-train scalability

Matched modules can be arranged across several cells while maintaining consistent access and connections.

Independent maintenance logic

Pressure taps and gas monitoring can distinguish dust loading from adsorbent breakthrough.

Applications

For semiconductor support air, laboratories and controlled industrial ventilation requiring both molecular contaminant removal and final high-efficiency particle control.

Solutions for Your Application

The carbon stage is replaced based only on pressure drop and breaks through unnoticed.Use a media-life calculation, sampling or downstream gas sensor independently of the particulate-stage pressure readings.

The three-stage train exceeds the available fan static.Add the clean and final resistance of every selected stage and increase face area or fan capacity before final sizing.
