Is there a time limit on the dust collection compliance guarantee?

The guarantee applies to the compliance inspection of the system as designed and installed. Whether the first inspection happens three months or twelve months after installation, the guarantee still applies. Normal wear and tear requiring filter replacement or component maintenance is not covered, but ongoing service plans are available.

What happens if we modify the dust collection system after installation?

Modifications made by your team or another contractor fall outside the original design scope. Industrial Clean Air Products can evaluate modifications and bring systems back into compliance as a separate project. The best approach is to consult before making changes to understand the compliance impact.

Does the compliance guarantee cover dust collection systems designed by others?

No. The guarantee only applies to systems designed, engineered, and specified by Industrial Clean Air Products. Existing systems can be evaluated and upgraded, and those upgrades carry their own guarantee, but systems designed or installed by others before involvement are not covered.

How is the pass-or-free guarantee different from a standard equipment warranty?

A standard equipment warranty covers manufacturing defects like motor failures or housing cracks. The pass-or-free guarantee covers system design compliance — whether the engineered solution including airflow, duct sizing, collector capacity, and explosion protection satisfies OSHA and NFPA requirements during inspection. Most companies only offer equipment warranties, not design compliance guarantees.

Is the pass-or-free compliance guarantee in writing?

Yes. The compliance guarantee is documented in the project agreement with clear terms so both the customer and Industrial Clean Air Products know exactly what is covered. The guarantee activates once the project is paid in full. It is a contractual commitment, not a verbal promise.

Plain English

What This Guarantee Actually Means

Most dust collection companies hand you a system and wish you luck when the inspector shows up. We do the opposite. We stake our payment on the outcome — your system either meets compliance standards or we keep working until it does, on our dime.

This isn’t a marketing gimmick with fine print. It’s how we’ve always operated because we believe the company designing the system should carry the compliance risk — not the facility paying for it. Curious how others in the industry handle this? Read what we found mystery shopping other dust collection companies.

The short version: We design it. We engineer it. We spec every component. Once the project is paid in full, if the system we designed doesn’t pass your OSHA or NFPA compliance inspection, we make it right at zero additional cost to you.

What’s Covered

Compliance Standards We Engineer To

NFPA 660

The new consolidated standard for combustible dust — enforceable since January 1, 2026. Covers dust hazard analysis, system design, explosion protection, housekeeping requirements, and ongoing management. This is the big one driving demand right now. Use our NFPA 660 checklist to see where your facility stands.

OSHA Compliance

Permissible exposure limits (PELs) for airborne particulates, general duty clause requirements, combustible dust National Emphasis Program (NEP) standards. We design systems that keep your facility on the right side of all of it.

Related Standards

NFPA 652 (fundamentals), NFPA 484 (combustible metals), NFPA 664 (wood dust) — all now consolidated under NFPA 660. We also address local fire marshal requirements and insurance carrier stipulations specific to your facility.

Our Process

Why We Can Back This Up

The guarantee works because we do the hard work before a wrench ever turns. Every project follows the same engineered approach — no shortcuts, no guessing.

Dust Hazard Analysis (DHA)

We start with lab-tested DHA to identify exactly what combustible dust hazards exist in your facility. No assumptions — real data from accredited testing on your actual materials. This is the foundation NFPA 660 requires, and it’s the foundation of every system we design. Understanding your dust’s Kst value and explosion severity determines every design decision that follows. If a DHA reveals problems with your current setup, we have a clear fix-it roadmap for failed dust hazard analysis.

Engineered System Design

Full engineering drawings, airflow calculations, duct sizing, collector specifications, and explosion protection requirements — all based on DHA results and your specific facility layout. Every component is spec’d to meet compliance before we quote a dollar.

Compliant Equipment Selection

We source collectors, ductwork, explosion venting, spark detection, and suppression systems that match the engineering specs — not whatever’s cheapest or easiest to get. Every piece of equipment has a compliance reason for being there.

Installation Oversight

Whether our contractor partners or your crew handles the install, we manage the process against the engineered drawings. That means field verification at key milestones — not a surprise visit at the end hoping it all went right.

Compliance Verification & Documentation

Before we call a project complete, we verify the system against OSHA and NFPA 660 requirements ourselves. You get full compliance documentation — DHA reports, engineering specs, equipment certifications, and inspection-ready paperwork. When the inspector arrives, you’re prepared.

Compliance-guaranteed systems typically range from $60,000 to $500,000+ depending on facility size and hazard class. Need to spread the investment? We offer financing options with zero down and fixed monthly payments. For a full breakdown, see our 2026 dust collection cost guide.

The Honest Answer

What Happens If Something Doesn’t Pass?

We’re not going to pretend inspections are always simple. Inspectors interpret codes differently. Local jurisdictions add their own requirements. Sometimes a fire marshal wants something specific that goes beyond the published standard.

Here’s what we commit to: if an inspector flags any part of a system we designed and specified, we address it. That might mean re-engineering a section, adding a component, or modifying ductwork. Whatever it takes to get your system to a passing inspection — we handle it and we pay for it.

We don’t argue about whose fault it is. We don’t send you a change order. We fix it because that’s the guarantee.

A couple things to know: The guarantee covers the system we design and specify, and it becomes active once the project is paid in full. If modifications are made to the system after installation without our involvement, or if a facility changes its processes in ways that affect dust generation, those fall outside the original scope. We’re always happy to help address those situations too — it’s just handled as a separate project.

Why It Matters

What’s Actually at Stake Without Proper Compliance

NFPA 660 exists because combustible dust explosions are preventable — but only if facilities have properly designed collection and protection systems. The standard consolidates years of lessons learned from real incidents into clear engineering requirements.

For facility managers and safety directors, the challenge isn’t understanding that compliance matters — it’s knowing whether the system you’re paying for will actually meet the standard. That’s the gap our guarantee closes.

You shouldn’t have to become a dust collection engineer to feel confident your facility is protected. That’s our job. The guarantee just makes sure we’re held to it.

Common Questions

Questions About the Guarantee

What specific inspections does the guarantee cover?

OSHA compliance inspections, fire marshal inspections related to dust collection and combustible dust hazards, and any inspection tied to NFPA 660 (or its predecessor standards 652, 484, 664) requirements. If an inspector is evaluating the dust collection system we designed and it doesn’t meet the applicable standard, we address it.

Is there a time limit on the guarantee?

The guarantee applies to the compliance inspection of the system as we designed and installed it. If your first inspection happens three months after install or twelve months after — the guarantee still applies. What it doesn’t cover indefinitely is normal wear and tear. Filters need replacing. Components need maintenance. We offer ongoing service plans for that, and many of our contractor partners handle it locally.

What if we modify the system after installation?

If your team or another contractor modifies the system — adding branches, removing components, changing ductwork — those changes fall outside the original design scope. We’re always willing to evaluate modifications and bring things back into compliance, but that would be handled as a separate project. The simplest approach is to call us before making changes so we can advise on compliance impact.

Does the guarantee cover systems you didn’t design?

No. The guarantee only applies to systems we design, engineer, and specify from the ground up. We can evaluate existing systems and recommend upgrades — and those upgrades would carry their own guarantee — but we can’t guarantee work that someone else designed or installed before we were involved.

How is this different from a standard warranty?

A typical equipment warranty covers defects in manufacturing — a motor fails, a housing cracks. That’s between you and the equipment manufacturer. Our guarantee is about the system design meeting compliance standards. It covers whether the engineered solution — airflow, duct sizing, collector capacity, explosion protection — actually satisfies OSHA and NFPA requirements during inspection. Those are two very different things, and most companies only offer the first one.

What do we need to do on our end to keep the guarantee valid?

First, the project needs to be paid in full — the guarantee is active once final payment is received. Beyond that, operate the system as designed and keep up with the recommended maintenance schedule we provide. That means running the collector during production, replacing filters on schedule, keeping blast gates in their designed positions, and not modifying the system without consulting us first. We provide clear maintenance documentation so there’s no ambiguity about what’s needed. Need service? Submit a maintenance request.

Do you put the guarantee in writing?

Yes. The compliance guarantee is part of our project agreement. It’s not a handshake — it’s documented in the contract with clear terms so both sides know exactly what’s covered. The guarantee activates once the project is paid in full.
