RLAF Booth & Workstation
PHARMINTECH Reverse Laminar Air Flow (RLAF) products are engineered to protect operator, product, and environment during powder handling tasks such as sampling and dispensing. Below are precise, catalog-ready descriptions, technical specifications, variants, safety features, validation notes, and selection guidance based strictly on your supplied data.
Reverse Laminar Air Flow Booth
The design combines downward laminar flow with containment strategies to protect the operator, the product, and the surrounding environment.
Purpose: Controlled environment for powder and bulk-material sampling and dispensing where product protection and reduced cross-contamination are required.
Key Specifications
- Construction: Powder-coated steel or stainless steel finish in SS 304 & SS 316
- Air Cleanliness: ISO Class 5 (Class 100) at work zone
- Air Velocity: 90 ± 20% FPM at the work surface
- Airflow Pattern: Vertical downward laminar flow with partial recirculation; dedicated exhaust to maintain a slight negative bias relative to adjacent areas if required.
- Filtration: Supply HEPA Filter H-14, Efficiency 99.999% down to 0.3 micron
- Monitoring: Audio-visual alarms driven by a digital differential pressure gauge
- Controls: Digital control panel, hour meter, LED status indicators, alarm for filter loading and airflow deviation.
Variants: Available in NON Flameproof | Flame proof construction with FLP electrical fittings
Applications: Large-batch powder sampling and dispensing, bulk material handling in pharmaceutical and chemical production
Solvent Dispensing Booth (FLP, 100% exhaust, Entry door)
This consist of 100 % Exhaust system which creates a negative pressure inside the booth. The Booth has a door for performing the operations in a closed booth.
Purpose: Safe handling and dispensing of flammable|volatile solvents; eliminate vapor accumulation and ignition risk.
Key Specifications
- Materials & construction: Flameproof / ATEX-certified construction; SS 304 / SS 316 / SS 316L
- Airflow: 100% exhaust (no recirculation) routed to a safe external discharge point or solvent abatement system.
- Filtration: HEPA H-14 for particulate capture on exhaust if required by downstream abatement; activated carbon or catalytic abatement may be required for solvent vapors
- Electrical: All electrical components to be FLP-rated; lighting and controls to meet ATEX/IECEx zones as specified.
- Access: Dedicated sealed entry door; pressure monitoring and visual/audible alarms for exhaust failure.
Reverse LAF Sampling Workstation
They create a continuous negative-pressure working area with two-stage filtration and controlled air bleeding to suppress dust clouds and capture particulates.
Key Specifications
- Construction: SS 304 / SS 316 / SS 316L
- Air Cleanliness: ISO Class 5 (Class 100) at work zone
- Air Velocity: 90 ± 20% FPM at the work surface
- Airflow Pattern: Vertical downward laminar flow with negative-pressure bleed of 10–15% of supply air
- Filtration: Two-stage filtration with pre-filter plus HEPA H-14, Efficiency 99.997% down to 0.3 micron
- Controls: Digital control panel with hour meter and LED status recommended (match other LAF controls)
Variants: Compact benchtop workstations sized for small-batch operations; optional flameproof/ATEX electrical package
Applications: Small-batch sampling, R&D sampling, pilot-scale dispensing, sterile handling of small volumes
Downflow Booth with Restricted Access Barrier System (RABS)
This consist of 100 % Exhaust system which creates a negative pressure inside the booth.
The Booth has a RABS Screen with Glove Ports for avoiding direct exposure to the product with medium OEM levels.
Purpose: Highest level of local containment and aseptic separation for critical sampling/dispensing where operator access must be restricted and contamination risk minimized.
Key Specifications
- Materials: SS 304 & SS 316 ; 4B finish internal surfaces.
- Air cleanliness: ISO Class 5 within RABS envelope; downflow laminar air with controlled exhaust.
- Airflow & containment: Downflow laminar air combined with RABS physical barrier; access panels and glove ports; pressure cascade to ensure containment.
- Filtration: HEPA H-14 supply; exhaust HEPA or appropriate containment filtration.
- Controls & validation: PLC or microprocessor control with cycle logging and integrated environmental sensors (particle, differential pressure, temperature, humidity).
