The Ductless Fume Hood FH1000(C) is a self-contained chemical containment system designed for laboratory applications requiring localized fume extraction and operator protection. This unit operates without external ductwork through an integrated filtration system and centrifugal blower, providing air velocities of 0.4-0.6 m/s across the work opening to contain and remove chemical vapors at the source.
The system features a 910×690×740mm internal workspace with 650mm maximum sash opening, accommodating standard laboratory procedures while maintaining consistent airflow containment. Built-in centrifugal blower with adjustable speed control delivers 136 m³/h airflow volume at noise levels ≤58 dB(A), suitable for laboratory environments requiring both containment performance and acoustic comfort.
How It Works
The ductless fume hood operates on the principle of localized capture and filtration of chemical vapors through negative pressure containment. Air is drawn through the work opening at controlled velocities of 0.4-0.6 m/s, creating a containment zone that prevents vapor escape into the laboratory environment. The integrated centrifugal blower maintains consistent airflow across the work surface, with speed adjustment capability to match specific application requirements.
Captured air passes through an internal filtration system before recirculation, removing chemical contaminants from the airstream. The self-contained design eliminates the need for external ductwork or building ventilation modifications, making it suitable for laboratories with limited infrastructure or temporary installations.
The 650mm maximum sash opening provides operator access while maintaining containment performance, with the work surface positioned at 900mm height for ergonomic operation during extended procedures.

Practical Tips
Verify face velocity at multiple points across the work opening using a calibrated digital anemometer, measuring at the plane of the sash opening.
Why: Ensures uniform containment performance across the entire workspace and identifies potential airflow irregularities.
Monitor filter condition through pressure differential measurements and visual inspection for saturation or breakthrough.
Why: Prevents loss of containment effectiveness and maintains optimal airflow performance throughout filter service life.
Keep equipment and materials at least 150mm back from the sash opening to prevent disruption of containment airflow patterns.
Why: Maintains effective vapor capture zone and prevents turbulence that could compromise containment performance.
Conduct initial containment verification with tracer gas testing before handling hazardous chemicals in the workspace.
Why: Confirms proper operation and containment effectiveness under actual operating conditions before exposure risk.
Check sash operation and sealing if containment performance appears compromised, ensuring proper closure and alignment.
Why: Sash position and sealing integrity directly affect airflow patterns and containment effectiveness.
Document airflow measurements and filter replacement dates to maintain performance history and predict maintenance needs.
Why: Enables proactive maintenance scheduling and provides evidence of proper equipment operation for compliance documentation.
Allow the system to operate for several minutes before beginning work to establish stable airflow patterns.
Why: Ensures consistent containment performance and allows airflow to stabilize before introducing chemical vapors.
Clean interior surfaces regularly with appropriate solvents to prevent chemical buildup and maintain visibility through the sash.
Why: Prevents accumulation of residues that could interfere with airflow or create contamination sources for subsequent procedures.

Background reading relevant to this product:
What types of chemicals can be safely handled in this ductless fume hood?
Suitability depends on the specific filtration media installed. Consult the filtration specifications and manufacturer guidelines for chemical compatibility. Typically suitable for organic solvents and general laboratory reagents, but not for highly toxic or corrosive compounds requiring specialized filtration.
How often do the filters need replacement?
Filter replacement frequency depends on chemical usage, concentration, and operational hours. Monitor filter condition through pressure differential measurements and replace when breakthrough occurs or pressure drop exceeds specifications. Typical replacement intervals range from 6-18 months under normal laboratory use.
Can the airflow velocity be verified and calibrated?
Yes, the adjustable speed blower allows optimization of airflow. Use calibrated anemometer or digital manometer to verify face velocity at multiple points across the work opening. Regular velocity mapping ensures consistent containment performance across the workspace.
What maintenance procedures are required?
Regular maintenance includes filter inspection and replacement, blower cleaning, sash operation verification, and airflow performance testing. Clean interior surfaces regularly and inspect seals for proper containment. Schedule annual containment testing to verify performance standards.
How does this compare to ducted fume hood systems?
Ductless systems offer installation flexibility and lower infrastructure requirements but are limited to specific chemical classes based on filtration capability. Ducted hoods handle broader chemical ranges but require permanent ventilation infrastructure and higher energy consumption.
What electrical requirements are needed for installation?
Consult product specifications for exact electrical requirements including voltage, current, and frequency specifications. Ensure adequate electrical capacity for blower motor and lighting systems, with appropriate grounding for safety compliance.
Can multiple users work simultaneously in this hood?
The 910mm internal width accommodates single-user operation for most procedures. Multiple users may interfere with proper airflow patterns and containment effectiveness. Design workspace layout and procedures for sequential rather than simultaneous use.
What containment testing methods should be used?
Use tracer gas testing with sulfur hexafluoride or similar compounds to verify containment performance. Conduct tests at various sash positions and with representative equipment configurations to ensure effective vapor capture under actual operating conditions.
