STJH-LOW-RESISTANCE-ULPA-U16-040

Low-Resistance ULPA Filter U16 0.40 in. w.g.

A balanced U16 membrane panel for fabs needing tighter particle control while limiting the pressure increase over U15.

مقدمة المنتج

This low-resistance U16 model targets facilities that need 99.99995% efficiency at MPPS but want to hold nominal clean resistance to 0.40 in. w.g. at 100 fpm. The 35 mm supported ePTFE pack provides a middle ground between the 0.33 U15 and 0.55 U17 versions. System selection should evaluate the actual quantity of panels and loaded operating point, not just the single-filter clean value.

الخصائص الرئيسية

Efficiency-energy balance

U16 lowers penetration by tenfold from U15 while adding a comparatively modest clean resistance at the published velocity.

Stable thin pack

Hot-melt spacing controls the 35 mm mini-pleat geometry for even airflow through the supported membrane.

Retrofit seal choices

Configurable aluminum frames allow the pressure-focused pack to match common dry or fluid-seal ceiling systems.

Applications

Designed for advanced microelectronics rooms and tool zones where U16 is required across meaningful ceiling area. The modest clean resistance supports energy control, provided the fan and terminal seals are commissioned for the complete array.

Solutions for Your Application

The facility wants U16 performance but cannot absorb the U17 pressure penalty.Select the documented 0.40 in. w.g. U16 tier and verify that its penetration limit satisfies the process requirement.

Filter replacement causes uneven velocities across an otherwise uniform ceiling.Keep frame depth and seal geometry consistent across the zone, then rebalance using measured face velocities after changeout.

الخيارات المتاحة

Specify actual face size, frame depth, gasket or gel side, knife-edge option, guard material and divider or port arrangement.
