The FH-PL series is a PP spray fume hood engineered for perchloric acid work and other
highly corrosive applications where conventional ducted hoods are not sufficient. An alkaline water
neutralization and circulation system behind the deflector intercepts acid gases before they reach the
exhaust duct, preventing high concentrations of perchloric acid residues from accumulating and creating
explosion or fire hazards.
The entire enclosure — body, liner, blower housing, and ductwork — is fabricated from polypropylene
using integral welding, providing uniform resistance to strong acids, alkalis, and corrosive vapors. The
built-in PP centrifugal blower maintains face velocity across the 0.3–0.8 m/s working range. A control
panel manages lighting, circuit switching, and air volume adjustment. The circulating water system
comprises an acid/alkali-resistant pump, dedicated water tank, and complete closed-loop circuit.
Standard inclusions are LED lighting, a chemical-resistant phenolic resin work surface, PP water and
gas taps, water sink, 4.3 m PVC exhaust duct, base cabinet, and waterproof sockets. The FH1800PL uses
dual blowers and dual exhaust ducts for its wider internal volume.

How It Works
The fume hood operates on the principle of directional airflow to capture and remove hazardous vapors at their source. Ambient laboratory air enters through the front sash opening and flows across the work surface at controlled velocities between 0.3-0.8 m/s. This airflow pattern creates a containment zone that prevents vapor escape while maintaining sufficient velocity to capture chemical emissions.
The integrated exhaust system draws contaminated air through internal ductwork at volumetric flow rates of 560-920 m³/h depending on model configuration. Variable airflow control allows optimization of capture velocity based on the volatility and toxicity of materials being handled. The exhaust stream requires connection to building ventilation systems or external blowers for proper disposal of captured contaminants.
Polypropylene construction provides chemical resistance against acids, bases, and organic solvents commonly encountered in laboratory applications. The material maintains structural stability under continuous airflow while resisting degradation from chemical exposure. Internal surfaces facilitate decontamination procedures between different chemical operations.

Practical Tips
Verify airflow velocity monthly using a calibrated anemometer at 6-9 measurement points across the sash opening.
Why: Airflow variations can develop over time due to filter loading or ductwork changes, compromising containment effectiveness.
Clean internal surfaces weekly with appropriate solvents to prevent chemical buildup and cross-contamination between procedures.
Why: Accumulated residues can affect airflow patterns and create secondary exposure hazards during subsequent operations.
Keep materials and equipment at least 6 inches back from the sash opening to maintain proper airflow patterns.
Why: Items placed too close to the opening can disrupt capture velocity and allow vapor escape into the laboratory.
Perform smoke visualization tests monthly to verify containment effectiveness and identify airflow disruptions.
Why: Visual confirmation of airflow patterns detects problems not apparent from velocity measurements alone.
If airflow seems inadequate, check for obstructions in ductwork and verify exhaust system capacity matches hood requirements.
Why: Inadequate airflow is often caused by external factors rather than hood malfunction, requiring systematic diagnosis.
Document airflow measurements and maintenance activities to establish performance trends and predict service needs.
Why: Historical data enables proactive maintenance and demonstrates due diligence for regulatory compliance documentation.
Allow hood to operate for 5-10 minutes before and after chemical procedures to ensure complete vapor removal.
Why: Purge times ensure all contaminated air is removed from the work zone before personnel access or equipment shutdown.

Background reading relevant to this product:
What exhaust system requirements are needed for proper operation?
Each model requires external exhaust capacity matching the specified volume (560-920 m³/h) with adequate static pressure to overcome ductwork resistance. Building ventilation systems or dedicated blowers must maintain consistent airflow regardless of atmospheric conditions.
How do I verify containment performance after installation?
Use calibrated anemometer to measure face velocity at multiple points across the sash opening, ensuring readings fall within 0.3-0.8 m/s range. Follow with smoke visualization testing to confirm proper airflow patterns and absence of reverse flow or turbulence.
What chemical compatibility limitations should be considered?
Polypropylene construction resists most acids, bases, and organic solvents but may be affected by strong oxidizing agents or aromatic hydrocarbons at elevated temperatures. Consult chemical compatibility charts for specific reagents and exposure conditions.
Can the airflow be adjusted during operation?
Yes, airflow velocity can be adjusted within the 0.3-0.8 m/s range using integrated controls. Adjustments should be made gradually and verified with instrumentation to ensure containment effectiveness is maintained throughout the operating range.
What maintenance procedures are required?
Regular cleaning of internal surfaces with appropriate solvents, periodic airflow verification, and inspection of sash operation and seals. Filter replacement schedules depend on usage and types of chemicals handled.
How much laboratory space is required for installation?
Allow minimum 30cm clearance on each side for service access, plus adequate rear clearance for exhaust connections. Ceiling height must accommodate 2450mm overall height plus ductwork connections.
What electrical requirements are needed?
Primary power for the hood system plus 500W capacity for internal outlets. Power consumption ranges from 770W to 1070W total depending on model configuration. Electrical installation must include appropriate circuit protection.
