Fan Law 2 for Techs with Adam Mufich

The Basics:

• What is CFM and static pressure really?
• How to measure total external static pressure properly
• Why inches of water column matters

Fan Law 2 Deep Dive:

• Breaking down the intimidating math into simple terms
• Fan Law 2 the simplified approach
• Real-world examples with actual field measurements

Game-Changing Applications:

• Filter pressure drop calculations at different airflows
• Evaporator coil pressure drop analysis
• How to predict total external static pressure before installation
• Backing into TSP using duct pressure measurements

Problem-Solving Scenarios:

• Why replacing a PSC motor with variable speed can create problems
• How proper equipment sizing dramatically reduces static pressure
• Component selection strategies for coils and filters
• Real examples showing 1″ static vs 0.64″ static with proper planning

Key Takeaways:

Adam reveals how static pressure and airflow move together but not proportionally – increasing airflow by 16% can increase static pressure by 33%! This explains why so many techs struggle with noisy systems and premature equipment failures.

Featured Tools & Techniques:

• Digital TrueFlow® Grid measurements
• Fan performance tables and plotting
• Component pressure drop ratings
• Strategic filter and coil selection
