10.Industrial Dust Collector Pricing Guide 2025 | Cost Drivers & Quick Estimator

1) What Makes Up “Price” for a Dust Collector?

  • CAPEX (Purchase): Collector body (cartridge/bag/ housing / pulse-jet), fan, control panel (VFD / ΔP-based cleaning / remote), HEPA (polishing stage), explosion protection (isolation/venting/suppression), materials (CS / SS304/316L / FRP), silencers/acoustic enclosures, installation & ducting, acceptance docs (FAT/SAT, PAO/DOP, IQ/OQ…).

  • OPEX (Operation): Electricity (∝ Airflow Q × ΔP / efficiency), filter media/consumables, compressed air, downtime & maintenance, spare inventory.

Rule of thumb: Nail Q (airflow) and ΔP (static pressure) first. Q×ΔP drives fan size, filter area, energy, and overall system class.

3) Airflow × Static Pressure ≈ 70% of the Price

(1) Source Airflow Q

QCMM=Vf (m/s)×A (m2)×60Q_{CMM} = V_f\,(m/s)\times A\,(m^2)\times 60QCMM​=Vf​(m/s)×A(m2)×60

  • Weighing/dumping face velocity: 0.5–0.8 m/s (use higher for fine dust)

  • Conveying velocity in ducts: 14–18 m/s general, 18–22 m/s metal chips

(2) Equivalent Length → ΔP
Straight pipe + vertical × (2–3) + elbows/tees (90° elbow ≈ 30–50D)
Add equipment losses (filter chamber / HEPA / silencer / hood) to get system ΔP.

(3) Power & OPEX

kW∝Q×ΔPη\text{kW} \propto \frac{Q \times \Delta P}{\eta}kW∝ηQ×ΔP​

→ If ΔP doubles (e.g., 0.9 → 1.8 kPa at the same 60 CMM), fan class and cost jump a tier—and so does energy.


4) Typical Systems & Price Bands (Indicative)


5) Quick Estimation Method (Copy into your RFQ)

  1. List hood sizes & face velocity → compute Q per point.

  2. Apply simultaneity factor (e.g., 0.7) → add 10–20% growth margin.

  3. Draw the worst branch → compute L_eq & ΔP (include equipment losses).

  4. Use Q × ΔP to select low/medium pressure or high-vac, and size the unit.

  5. Add required options: ePTFE/anti-static/hydrophobic, HEPA, ex-proof, materials, noise, installation.

  6. Get a price band; lower OPEX with VFD + ΔP-based cleaning.

All are indicative bands; final pricing depends on site and vendor quotes.


7) FAQ

  • Why can two 60-CMM quotes differ by 2×?
    Different ΔP (ducts/elbows/hoses), A/C & media, HEPA, ex-proof, materials, installation.

  • What info should I send for accurate quoting?
    Use this guide’s checklist: airflow, ducting sketch, powder properties, materials, return air, acceptance.

  • Cheap media vs. ePTFE membrane?
    For fine/sticky dust or return air, ePTFE/nano stabilizes ΔP and reduces penetration—often lower TCO.

  • Where to place HEPA?
    Main filter → Fan → HEPA, with PAO/DOP integrity test & ΔP baseline.

  • Do I always need an explosion-proof model?
    Follow zoning & system safety: anti-static media + grounding/equipotential, isolation/venting/suppression, procedures; electrics by Zone.


8) Pitfalls to Avoid

  • Choosing by motor HP instead of the fan curve vs. system curve (Q×ΔP).

  • Using high-vac small flow for large hoods—poor capture.

  • Ignoring the worst branch—commissioning shows big flow loss.

  • No ΔP baseline & thresholds—maintenance by guesswork.

  • “Explosion-proof = change media only” mindset—must design isolation/venting/suppression + grounding as a system.


9) Decision Tree: Picking the Right Collector

  1. Define process & powder (size/sticky/oily/combustible).

  2. List inlets & face velocity → Q; draw worst path → ΔP.

  3. Classify low / medium pressure / high-vac; choose cartridge / baghouse / high-vac.

  4. Select media (ePTFE / anti-static / hydrophobic).

  5. Decide on HEPA, ex-proof, materials, noise.

  6. Include installation & acceptance scope in RFQ.

  7. Use the price table to set a budget band, then refine with vendors.
