The Ductless PP Fume Hood FH1000(PD) FH1500(PD) is a polypropylene laboratory ventilation system designed for containment and filtration of chemical vapors and particulates during routine analytical procedures. The unit features a built-in centrifugal blower system with active carbon filtration, providing 230 m³/h airflow volume at face velocities of 0.3-0.8 m/s through a 640 mm maximum sash opening.
The hood operates as a recirculating system, drawing contaminated air through dual active carbon filters before returning cleaned air to the laboratory environment. The 980×606×688 mm internal workspace accommodates standard laboratory equipment and procedures, while integrated LED illumination provides ≥400 lx working light levels. Optional accessories include water and gas taps, sink installation, and HEPA filtration for enhanced particulate removal.
How It Works
The fume hood operates on the principle of negative pressure containment and filtration. The built-in centrifugal blower creates airflow from the laboratory environment into the hood workspace, drawing chemical vapors and particulates away from the operator. Air enters through the front opening at velocities between 0.3-0.8 m/s, ensuring effective capture of contaminants generated within the workspace.
Contaminated air passes through dual active carbon filters that adsorb organic vapors and chemical contaminants through physical and chemical adsorption processes. The activated carbon provides a large surface area for vapor molecule interaction, effectively removing volatile organic compounds from the airstream. After filtration, cleaned air is recirculated back into the laboratory through the blower system at 230 m³/h flow rate.
The polypropylene construction provides chemical resistance to acids, bases, and organic solvents commonly used in laboratory procedures. The ductless design eliminates the need for external ventilation connections, allowing flexible placement within laboratory spaces while maintaining containment effectiveness through the internal filtration system.

Practical Tips
Verify face velocity measurements across the entire sash opening using a calibrated anemometer at multiple points.
Why: Ensures uniform containment performance across the workspace entrance.
Replace active carbon filters when breakthrough detection indicates saturation or according to manufacturer schedule.
Why: Saturated filters lose adsorption capacity and compromise vapor containment effectiveness.
Keep the sash at minimum opening height consistent with procedure requirements to optimize containment.
Why: Lower sash positions maintain higher face velocities and improve capture efficiency.
Use appropriate respiratory protection when changing filters or performing maintenance procedures.
Why: Contaminated filters may release accumulated vapors during handling and replacement.
Document filter change dates and chemical usage to establish appropriate replacement schedules.
Why: Usage tracking helps optimize maintenance intervals and prevents filter breakthrough.
Check for proper filter installation and sealing if airflow measurements decrease below specifications.
Why: Improperly seated filters create bypass pathways that reduce containment effectiveness.
Allow the blower system to run for several minutes before beginning procedures to establish stable airflow patterns.
Why: Steady-state airflow conditions ensure consistent vapor capture performance.
Clean the interior surfaces regularly with compatible solvents to prevent chemical buildup.
Why: Accumulated residues can interfere with airflow patterns and create contamination sources.

Background reading relevant to this product:
What types of chemicals can be safely used with the active carbon filtration system?
The active carbon filters effectively remove most organic vapors and volatile compounds. Consult the filter specifications for specific chemical compatibility. Highly corrosive acids or bases may require additional containment measures.
How often should the active carbon filters be replaced?
Filter replacement frequency depends on usage intensity and chemical types. Monitor filter saturation indicators if available, or establish replacement schedules based on breakthrough testing for your specific applications.
Can the unit be connected to external exhaust systems?
This is a ductless recirculating system designed for internal filtration. External exhaust connection would require consultation with the manufacturer regarding airflow balance and system modifications.
What is the maximum weight capacity for equipment inside the hood?
Consult product datasheet for specific weight limits. The workspace dimensions of 980×606×688 mm accommodate standard analytical equipment, but weight distribution should be considered for optimal airflow.
How do I verify the face velocity meets containment requirements?
Use calibrated airflow measurement instruments such as thermal anemometers or smoke tube visualization to verify the 0.3-0.8 m/s face velocity specification across the sash opening.
Is HEPA filtration necessary for my applications?
HEPA filtration is optional and recommended for applications involving fine particulates or biological materials. The standard active carbon filters primarily target vapor containment.
What maintenance procedures are required for optimal performance?
Regular filter replacement, periodic airflow verification, LED lamp inspection, and blower system cleaning according to manufacturer maintenance schedules ensure consistent containment performance.
