FAQ: Combustible Dust Central Vacuum System

❓ How do I know if my dust is combustible?

✅ Answer: Test your dust using ASTM E1226 (Go/No-Go Screening) or ASTM E1515 (Chemical Analysis). Common combustible dusts include:

• Food: Flour, sugar, starch, coffee, cocoa, dairy powders.
• Wood: Sawdust, MDF, plywood, paper.
• Metals: Aluminum, magnesium, titanium, zinc.
• Chemicals: Plastics, rubber, sulfur, coal.

💡 Pro Tip: If your dust forms a cloud in the air, it’s likely combustible.

❓ What’s the difference between a central vacuum and a portable industrial vacuum?

✅ Answer:

❓ How often do filters need replacement?

✅ Answer: With our pulse-jet cleaning system, filters last 2–5 years depending on dust type. For example:

• Food/Wood Dust: 3–4 years
• Metal Dust: 2–3 years (abrasive)
• Pharmaceuticals: 4–5 years (low volume)

💡 We offer filter replacement subscriptions to ensure compliance.

❓ Can the system be retrofitted into an existing plant?

✅ Answer: Yes! Our engineers design custom piping layouts to integrate with your current setup. Key considerations:

• Piping Material: Galvanized steel (standard), stainless steel (food/pharma), or aluminum (lightweight).
• Pickup Points: Strategically placed near dust generation sources (e.g., conveyors, mixers, saws).
• Ductwork Routing: Avoid sharp bends (<45°) to maintain airflow.
• Space Requirements: Central unit needs 100–500 sq. ft depending on capacity.

✅ Free site assessment to determine the best configuration for your facility.

❓ What’s the lead time for installation?

✅ Answer:

• Standard Systems (Stock): 2–4 weeks (shipping from China).
• Custom Systems: 4–6 weeks (engineering + manufacturing).
• Installation: 1–3 weeks (depending on facility size).

🚀 Fast-track option: Expedited shipping in 10–15 days (additional fee).

❓ Do you offer financing or leasing options?

✅ Answer: Yes! We partner with global financing providers to offer:

• Leasing: $0 down, 24–60 month terms.
• Equipment Financing: Fixed rates from 4–7% APR.
• Rent-to-Own: Try the system for 6–12 months before committing.

❓ How does the system handle wet or sticky dust?

✅ Answer: For moist, sticky, or hygroscopic dusts (e.g., sugar, starch, some chemicals), we offer:

• Pre-Separators: Cyclone separators remove 90% of large/heavy particles before the filter.
• Anti-Stick Filters: PTFE-coated or nanofiber media prevents clogging.
• Rotary Valves: Air-lock discharge for wet or cohesive dusts.
• Heated Piping: Optional for high-humidity environments.
