Our Expertise

We combine aeronautical and mechanical engineering principles with 20+ years of field experience to design systems that perform reliably under the harshest conditions.

Expertise Areas:

• CFM Calculation & Sizing: Precise airflow requirements accounting for dust type, particle size, operation, and environmental factors. Not oversized, not undersized - optimized.
• Ductwork Analysis: Pressure drop calculations, velocity requirements, equivalent length fittings, friction loss modeling. Proper design eliminates 30-50% of unnecessary system losses.
• Fan Selection: Matching fan curves to system requirements, static pressure calculations, power requirements, noise control. We specify fans that perform reliably under actual operating conditions.
• Filtration Technology: Media selection (polyester, PTFE, aramid, microglass), baghouse vs. cartridge evaluation, filter sizing, cleaning system optimization.
• Hopper & Discharge Design: Preventing bridging and compaction, abrasive recovery systems, material flow optimization.
• Explosive Hazard Assessment: NFPA 654 compliance, inerting systems, spark detection, explosion venting sizing.

We specialize in helping facilities achieve and maintain full compliance with OSHA standards - a complex, multi-faceted challenge that requires expertise across engineering, industrial hygiene, and regulatory requirements.

OSHA Standards Expertise:

• Silica Standard (29 CFR 1910.1053): Comprehensive understanding of exposure limits (50 µg/m³ PEL, 25 µg/m³ action level), engineering control requirements, respiratory protection programs, medical surveillance, and worker training requirements.
• Respiratory Protection (29 CFR 1910.134): Written program development, fit testing protocols, respirator selection for dust hazards, training and certification requirements.
• Medical Surveillance: Baseline examination protocols, periodic exam intervals, abnormal result follow-up procedures, 30-year record retention requirements.
• Hazard Communication: SDS requirements, labeling procedures, worker information and training documentation.
• Personal Air Sampling: Designing monitoring programs, isokinetic sampling methodology, lab analysis interpretation, trend analysis.
• Noise Exposure (29 CFR 1910.95): Audiometric testing, hearing protection programs, control measure selection.

What We Provide:

• Compliance audit and gap analysis
• Exposure assessment and monitoring program design
• Engineering control recommendations and implementation
• Respiratory protection program setup
• Medical surveillance program coordination
• Worker training material and delivery
• Documentation and record management
• Ongoing compliance verification and updates

Air Quality Expertise:

• EPA Standards: NAAQS compliance (PM10, PM2.5), NESHAP applicability determination, state-specific standards interpretation.
• Permits & Regulations: Title V permit requirements, general permit eligibility, state air quality agency coordination.
• Emission Testing: EPA Method 5 interpretation, stack testing protocol development, continuous monitoring system specification.
• Emission Calculations: Material balance approach, emission factor methodology, locality-specific standards compliance.

We Help With:

• Determining permit requirements for your facility
• Designing systems to meet local emissions limits
• Preparing documentation for permit applications
• Coordinating stack testing and analysis
• Interpreting test results and maintaining compliance

Beyond initial design, we excel at optimizing existing systems and diagnosing problems that others can't solve.

Optimization Services:

• System Audit: Comprehensive evaluation of design, performance, maintenance practices, compliance status.
• Performance Analysis: Pressure drop trending, CFM verification, energy consumption analysis, efficiency assessment.
• Optimization Recommendations: Filter upgrade options, pulse jet tuning, ductwork improvements, energy efficiency upgrades, maintenance program refinement.
• ROI Analysis: Quantifying payback on optimization investments through energy savings, filter life extension, labor reduction.

Troubleshooting Expertise:

• High Pressure Drop: Diagnosis and resolution of clogging, filter damage, cleaning system failures.
• Low Airflow: Fan performance issues, ductwork blockages, undersizing identification.
• Dust Leakage: Seal integrity, housing damage, filter seating problems.
• Motor Issues: Electrical problems, bearing wear, overheating, control failures.
• Unusual Operation: Vibration, noise, abnormal sounds indicating imminent failure.
• Compliance Gaps: Worker exposure exceeding limits, environmental emissions non-compliance.

Many of our "impossible" troubleshooting cases arise from systems that were undersized, improperly designed, or not maintained correctly. We diagnose root causes and implement lasting solutions.
