Dedusting Tunnels

PHARMINTECH De‑dusting Tunnel is engineered to effectively remove dust and particulate matter from materials entering controlled environments. It ensures that raw materials, containers, and equipment are free from contaminants before entering cleanrooms, making it ideal for pharmaceutical, biotechnology, food, and other sensitive manufacturing facilities.
Design & Functionality
- Purpose: Prevents particulate ingress into cleanrooms by subjecting incoming materials to high‑velocity air jets and brushing action.
- Airflow Principle:
- Vertically downwards jets dislodge dust from the top surfaces.
- Horizontal re‑circulatory jets sweep particles from the sides and undersides.
- The brushing system ensures mechanical removal of stubborn dust.
- Conveyance: Motorised conveyor moves materials steadily through the tunnel, ensuring uniform exposure to air jets and brushes.
- Containment: Vinyl curtains at entry/exit minimise particle escape.
- Collection: Dust collector tray gathers dislodged particles for safe disposal.
Key Specifications
- Construction: Stainless Steel SS 304 / SS 316 / SS 316L
- Air Velocity: 4000 ± 20% FPM for effective particle removal
- Conveyor System: Motorized belt with integrated brushing mechanism
- Nozzles: SS 304 precision nozzles for uniform air distribution
- Airflow: Vertically downwards + horizontally re‑circulatory
- Controls: PLC controller with sensors for cycle timing, conveyor speed, and safety interlocks
- Accessories: Dust collector tray, vinyl curtains, emergency stop switches
- Safety: Emergency switches and interlocked access doors for operator protection
Operational Flow
- Loading: Materials are placed on motorized conveyor at the tunnel entry.
- Curtain Seal: Vinyl curtains reduce cross‑contamination between zones.
- Air Jet & Brushing: High‑velocity air jets + brushing system remove dust from all surfaces.
- Re‑circulation: Horizontal airflow ensures particles are swept away from sides and undersides.
- Collection: Dust particles captured in the collector tray.
- Exit: Cleaned materials exit through the vinyl curtain into the controlled environment.
Benefits
- Ensures particle‑free entry into cleanrooms.
- Reduces risk of cross‑contamination and improves GMP compliance.
- Automated operation with PLC control for consistency and traceability.
- Durable construction with SS 304 / SS 316L for long service life.
- Safety features (emergency switches, curtains, sensors) protect operators and the environment.
Applications
- Pharmaceutical manufacturing (API, formulations, sterile facilities)
- Any facility requiring dust‑free material transfer
