Protecting People, Processes, and Precision Since 1976

In every lab and cleanroom environment, safety isn’t negotiable – it’s engineered. Whether you’re handling volatile solvents in a biotech lab, managing corrosive vapors in semiconductor fabrication, or ensuring regulatory compliance in pharmaceutical production, a properly designed fume hood is your first line of defense.

At Plastic Design Industries (PDI) in North Chelmsford, Massachusetts, we’ve spent nearly five decades perfecting custom plastic fabrication for the region’s most demanding industries. From biomedical and pharmaceutical to microelectronics and photonics, PDI’s custom fume hoods are built to protect both people and processes without compromising precision or productivity.

What a Fume Hood Actually Does (and Why It Matters)

Why Custom Fume Hoods by PDI Keep New England Lab Facilities Safe and Compliant

A fume hood is a ventilated enclosure that draws hazardous fumes, vapors, and dust away from the operator and safely exhausts them from the workspace. It’s not just equipment; it’s a critical engineering control that keeps your environment compliant and your team protected.

Fume hoods are designed to:

  • Capture airborne contaminants before they reach breathing zones.
  • Contain chemical vapors, powders, and corrosive gases.
  • Exhaust those hazards through properly filtered or ducted systems.
  • Comply with strict OSHA, NFPA, and ANSI/ASHRAE 110 performance standards.

When built right, a fume hood balances airflow, visibility, ergonomics, and containment efficiency. When built wrong, it becomes a false sense of security.

The PDI Difference: Built for Your Process, Not the Other Way Around

Most suppliers offer standard models. PDI builds fume hoods around your unique workflow, tailored to chemical compatibility, process layout, and airflow specifications. One solution we offer is our slope-front fume hoods, designed for improved visibility, ergonomic access, and containment efficiency.

Why Industry Leaders Choose PDI Fume Hoods

Custom Design Expertise

Every hood is fabricated in-house using precision CNC routing, laser cutting, and plastic welding. Whether you need a benchtop exhaust system or a full-room containment solution, PDI engineers it to spec, right down to the baffles and sash mechanics.

Material Mastery

PDI’s experience in acrylics, polypropylene, PVC, PVDF, and other chemical-resistant plastics ensures long-term durability and corrosion resistance, even under the toughest process conditions.

Compliance Confidence

PDI designs with OSHA, NFPA, and ANSI standards in mind, helping you pass inspections, reduce downtime, and protect your investment.

Regional Responsiveness

Located in North Chelmsford, MA, PDI serves the greater Boston and New England manufacturing corridor, offering faster delivery, local on-site support, and lifetime service relationships that offshore suppliers simply can’t match.

Signs Your Facility Needs a Fume Hood Upgrade

If your fume hood hasn’t been inspected or re-certified in the past year, it may not be performing at its best. Keep an eye out for these common performance indicators:

  • Airflow monitors that frequently alarm or show inconsistent readings.
  • Difficulty maintaining face velocity or containment.
  • Excess condensation, corrosion, or chemical staining inside the chamber.
  • Operators storing items in the hood (a common but dangerous airflow blocker).
  • Noise, vibration, or draft changes near the work area.

A PDI site evaluation can determine whether you need replacement components, retrofitting, or a complete system redesign.

Efficiency Meets Safety: Designing for the Modern Lab

Fume hoods are notorious energy consumers. A single conventional hood can exhaust as much conditioned air as several offices combined. PDI integrates Variable Air Volume (VAV) options and energy-conscious design choices, helping facilities cut HVAC costs while maintaining containment integrity.

Combine that with PDI’s precision fabrication and high-performance plastics, and you get a solution that’s as sustainable as it is safe.

Partnering with PDI: Made in Massachusetts, Trusted Everywhere

Since 1976, Plastic Design Industries. has remained New England’s oldest and largest plastic fabrication house, trusted by world-class labs and manufacturers across Massachusetts, Connecticut, Rhode Island, and beyond.

Our commitment to precision and partnership means you’re never buying equipment; you’re investing in performance.


“We design equipment that protects people, preserves processes, and performs flawlessly under pressure. That’s what 50 years of experience delivers.”
