STJH-SLIM-HEPA-H14-12IN

Slim HEPA Filter H14 with 12 in Collar

A 4.75-inch shallow H14 ceiling module with a larger 12-inch duct connection for lower inlet velocity.

12 in inlet collar
4.75 in overall depth
Integrated airflow diffusion

Introduction de produit

This model retains the slim 41 mm H14 pack and 4.75 in module depth but increases the duct collar to 12 in. The larger connection provides more inlet area for a given branch airflow and can ease duct velocity or connection losses where ceiling space allows the wider collar. An integrated diffusion disc spreads incoming air across the filter face behind the protective grille.

Key Features

Larger inlet area

The 12-inch collar accommodates branches selected to reduce connection velocity or local entry loss.

Shallow body retained

Increasing collar diameter does not change the 41 mm pack or low-profile module depth.

Even face supply

The internal diffusion disc redirects collar air across the HEPA pack instead of concentrating it beneath the inlet.

Applications

Selected for pharmaceutical, hospital and controlled manufacturing ceilings that have very little vertical room but use a 12-inch supply branch. Compare actual branch airflow, available collar diameter and neighboring services before choosing it over the narrower 10-inch model.

Solutions for Your Application

A 10-inch terminal collar creates excessive connection velocity at the planned branch flow.The 12-inch inlet offers greater connection area while the module remains only 4.75 in deep.

The larger collar conflicts laterally with cable trays or sprinkler pipework.Coordinate the 12-inch collar footprint and bend radius in the reflected ceiling and above-ceiling service layout.

Options disponibles

Confirm face module size, diffusion-disc control, 12-inch duct takeoff position, grille finish and ceiling-support details.
