Case Study: Repeat Order from Pakistan – Polypropylene Fume Hood with Charcoal Filtration

Market Background

In Pakistan, laboratories in universities and industrial testing facilities traditionally rely on ducted fume hoods. However, limitations in building structure and ventilation layout often lead to challenges in airflow control and high retrofit costs.

As a result, there is increasing demand for ductless fume hoods with integrated filtration systems, enabling localized air treatment and safer operation.

The client in this case is a long-term partner specializing in laboratory equipment supply, serving chemical analysis and material testing sectors.

Client Needs and Application Scenarios

The equipment was used for laboratory upgrades, mainly involving:

• Organic solvent handling (VOCs release)
• Acid and alkali reagent preparation
• Small-scale reaction experiments

Key technical concerns included:

• Local filtration without complex ducting
• Operator protection via enclosed operation
• Stability in corrosive and humid environments

Our Solution (PFH-1500 Fume Hood)

Structural Design

• Dimensions: 1500 × 750 × 2200 mm
• Front & bottom thickness: 40 mm
• Side thickness: 30 mm
• Top & back thickness: 20 mm
• Removable front observation window with glove ports
• Side operation windows

This configuration supports a semi-enclosed workspace to limit gas escape.

Filtration & Ventilation

• Multi-stage filtration:
  • Primary filter
  • High-efficiency filter
  • Charcoal filter (for VOC adsorption)
• Built-in exhaust fan
• Independent airflow circulation

Performance depends on gas type, concentration, and operating conditions.

Functional Features

• Integrated lighting system
• Sterilization module
• Power supply with safety protection

Client Feedback

After installation, the client reported:

• Improved odor containment during solvent operations
• Effective isolation using glove ports in small-scale experiments
• No visible corrosion of PP structure under acid/alkali exposure

The client also noted improved flexibility without modifying the existing ventilation system.

Summary (Key Technical Parameters)

• Corrosion-resistant PP structure
• Shielding thickness: 20–40 mm
• Multi-stage filtration (primary + HE + charcoal)
• Built-in exhaust system
• Glove-based sealed operation

Conclusion

This repeat order from a Pakistani client demonstrates that ductless, filtration-based fume hoods are becoming a practical complement to traditional ventilation systems, especially in retrofit scenarios. Parameter-driven configuration enables better alignment with specific laboratory conditions.
