Cleanroom Equipment's -DEMO : DAH Healthcare

Cleanroom Equipments

DAH Healthcare Solution Pvt. Ltd. designs and manufactures a comprehensive range of cleanroom equipment engineered to maintain contamination control, protect products and personnel, and ensure consistent performance in classified environments. All equipment is designed considering airflow dynamics, filtration efficiency, ease of cleaning, and validation requirements.

Static Pass Box

Static Pass Boxes are non-powered material transfer units used between cleanroom areas of different cleanliness classifications. They are designed to prevent cross-contamination during material movement while maintaining pressure integrity between rooms.

Dynamic Pass Box

Dynamic Pass Boxes are powered material transfer units equipped with HEPA filtration to actively maintain clean conditions during transfer operations. These units are used where higher cleanliness assurance is required.

Airflow & Filtration

Vertical laminar airflow pattern.
Pre-filter (G4) and terminal HEPA filter H14.
Uniform air velocity across working area.

Construction & Controls

SS 304 / SS 316 construction.
Electronic interlocking with control panel.
Differential pressure indicator / magnehelic gauge.
Validation ports for testing.

Performance Objective

Ensures ISO Class 5 conditions inside the chamber during operation.
Minimizes particle ingress during material transfer.

Air Shower Systems (Personnel & Material)

Air Showers are installed at entry points to cleanrooms to remove loose surface contaminants from personnel or materials before entry into controlled environments.

Design Features

High-velocity air jets positioned strategically on side walls and/or top.
SS or powder-coated GI/MS construction.
Automatic door interlocking system.

Operational Sequence

Door interlock ensures one-door operation.
Timed air shower cycle.
Emergency stop and safety features.

Laminar Air Flow Work Station

Laminar Air Flow units create localized ISO Class 5 clean zones by supplying unidirectional airflow through HEPA filtration. These units are critical for sterile and contamination-sensitive operations.

Types Available

Vertical Laminar Air Flow units.
Horizontal Laminar Air Flow units.
Ceiling-suspended laminar airflow units

Technical Characteristics

HEPA H13 / H14 terminal filtration.
Uniform airflow velocity (typically 0.36–0.54 m/s).
Low turbulence and minimal particle entrainment.

Applications

Sterile filling operations.
OT critical zones.
Laboratory and quality control activities.

Sampling & Dispensing Booths

Sampling and Dispensing Booths are designed for safe and controlled handling of powders and active ingredients, protecting both the operator and the product from contamination.

Airflow Principle

Reverse laminar airflow or downflow design.
Negative pressure containment.
Controlled exhaust airflow.

Design Features

HEPA-filtered supply and exhaust air.
Operator safety with controlled exposure levels.
Ergonomic working height and visibility.

Applications

Raw material sampling.
Weighing and dispensing operations.
Pharmaceutical and chemical processing areas.

Fan Filter Unit

FFUs are ceiling-mounted filtration units used in modular cleanrooms to provide localized HEPA-filtered airflow and achieve required cleanliness classifications.
