Laminar Flow and Containment Equipment
Laminar Flow Storage Cabinet
A stationary filtered cabinet that keeps particle-sensitive materials under continuous positive clean airflow between handling operations.
- Positive-Pressure Clean Storage
- Compartmented Access Doors
- Perforated Airflow Shelves
- Continuous Filter Monitoring
Product Introduction
This cabinet provides clean storage rather than an open working surface. A top or rear fan-filter unit supplies positive filtered air through perforated shelves, and low return or relief paths maintain circulation across the stored contents. Individual compartment doors can reduce disturbance when one shelf level is accessed. The cabinet may be built from stainless steel, static-dissipative PVC or other cleanroom-compatible materials according to the stored items.
Key Features
Perforated shelves distribute airflow through the full cabinet height.
Positive internal pressure reduces room-air infiltration at small door gaps.
Adjustable shelf rails accommodate changing container and tray heights.
A filter-pressure indicator supports routine condition monitoring.
Customer Product Concerns
Stored products need clean airflow between operations without exposing every shelf whenever one item is retrieved.
Opening one large door exposes the entire cabinet.Separate compartment doors localize each access event.
Upper shelves receive more airflow than lower shelves.Perforated shelves and balanced relief openings preserve vertical distribution.
Tray heights change between batches.Removable rails let shelves be repositioned without modifying the cabinet shell.
Filter loading is unnoticed during long storage periods.A pressure display or alarm makes airflow resistance visible.
Typical Applications
Clean component storageOptical part stagingSterile packaging suppliesElectronics work-in-process holding
