Dust Collection Calculator
Professional dust collection calculator for woodworking shops. Calculate CFM requirements, ductwork sizing, static pressure, and system design with comprehensive air filtration optimization strategies.
⚠️ HEALTH & SAFETY NOTICE
Proper dust collection is critical for health and safety. Wood dust can cause respiratory issues and fire hazards. Follow OSHA guidelines, use appropriate filtration, and ensure adequate air velocity for effective dust capture.

System Analysis
Configure your shop dimensions, equipment, and ductwork specifications to calculate comprehensive dust collection system requirements and optimization strategies.
CFM Requirements
Calculate precise cubic feet per minute requirements for each tool and overall shop ventilation for effective dust capture and air quality.
Ductwork Sizing
Optimize duct diameter and layout for proper air velocity, minimal pressure loss, and efficient dust transport throughout the system.
Static Pressure
Calculate system static pressure losses through ductwork, fittings, and filters to ensure adequate blower performance and efficiency.
Filter Selection
Choose appropriate filtration systems based on dust type, particle size, and air quality requirements for optimal health protection.
System Optimization
Balance airflow, minimize energy consumption, and maximize dust collection efficiency through proper system design and component selection.
Safety Compliance
Ensure compliance with OSHA standards, NFPA codes, and industry best practices for workplace air quality and fire prevention.
Frequently Asked Questions
CFM = Tool CFM + Ambient Air Changes. Each tool has specific CFM requirements (table saw ~350 CFM, planer ~800 CFM). Add shop volume × air changes per hour (typically 6-8 ACH) for ambient dust control.
Main ducts: 6-8" for most shops. Branch ducts: 4-6" depending on tool requirements. Maintain 3500-4000 FPM air velocity in ducts to prevent dust settling. Larger ducts reduce pressure loss but cost more.
Most dust collectors handle 6-10" of static pressure. Calculate losses: straight duct (0.1"/10ft), elbows (0.5-1.5" each), filters (1-4"), and fittings. Keep total under your blower's capacity.
Bag filters: economical, good for large particles. Cartridge filters: better fine dust capture, easy cleaning. Cyclone separators: pre-filter for heavy debris. HEPA: maximum filtration for health-critical applications.
Monitor pressure drop across filters. Clean cartridge filters when pressure increases 2-3" above clean filter. Replace when cleaning becomes ineffective. Bag filters typically last 6-12 months depending on usage.
Ensure adequate capture velocity at tool ports, ground all metal ductwork to prevent static buildup, use spark-resistant materials near sanders, maintain proper air changes for ambient dust control, and follow OSHA PEL limits.
