During negative air machine calculator and restoration jobs, negative air machines can be used to filter and contain airborne contaminants like dust, fumes, smoke, mold spores, and pathogens during the cleanup process. These machines are also known as air scrubbers and they are equipped with HEPA filters to recirculate or exhaust contaminated air depending on the job type.
Optimizing Air Quality: Using a Negative Air Machine Calculator for Effective Solutions
Negative air machines can be placed inside a room to recirculate the air or connected to flexible ducting to exhaust contaminated air out of a space. This can help control dust, lead, and other debris in abatement and construction projects. Negative air machines are also used to create negative pressure for patient isolation in healthcare facilities to prevent the spread of viruses and other infectious pathogens.
Before you purchase or rent a negative air machine, it is important to calculate how many air changes it will provide in a given time period. This can help you determine how much power or how large of a machine to purchase. To calculate the amount of air a negative air machine can change in an hour, start by finding the machine’s cubic feet per minute (CFM) rating. Then divide this number by the building’s volume in cubic feet to find how many times the machine will change the air in an hour.
For example, a CFM rating of 500 divided by a room’s volume in cubic feet is equal to 6 air changes an hour. This is the industry standard and can be a good guideline for what you should expect to see from your equipment.
