Total External Static Pressure Testing T E S P вђ Johnstone Supply Static pressure tip, low resistance application, furnished with two (2) hex jam nuts and two (2) mounting washers for duct mounting and with 1 8" npt pipe thread for pressure connection. 1 3 days * $77.40. An hvac technician taking a static pressure measurement. step 2: drill test ports using a 3 8′ drill bit with a metal piercing tip. a bullet tip drill makes a clean round port. so make sure to use your drill bit sheath (described above) to help prevent you from drilling into the coil.
Use Static Pressure Responsibly Hvac School A static pressure tip is a small metal tube about four inches long. it costs around $10 to $15 and is available across the industry. pressure in the duct system called velocity pressure and diverts it away from the small holes near the tip. this action allows only static pressure to enter the tip and display on the manometer. Now, before you drill a hole in the ductwork to insert a static pressure tip, verify system cleanliness by checking the filter, the coil (on both supply and return sides), and blower wheel. once you confirm the cleanliness, you can make a ¼” drill hole at the appropriate locations depending on the application. Step 4: read the supply or positive ( ) static pressure by inserting the static pressure tip into the test port with the tip facing into the airflow. the magnet on the tip will hold it in place while the value is read and recorded. this measurement is the pressure the fan is “seeing” on the supply side of the system. Static pressure tip facing into airflow. when measuring system pressures, the static pressure tip reads most accurately when facing directly into airflow. the purpose of this tip is to break up the added pressure of air movement and allow a direct reading of static pressure. this detail is more important when air velocity is higher.

Static pressure is measured in inches of water column (“wc) and is the amount of pressure needed to displace one inch of water in a water manometer. magnehelic is a brand name for a high quality dwyer analog pressure gauge that comes in many different scales. many techs will already have a high quality digital differential manometer (like the. Static pressure pickups. static pressure pickups mount to walls or ceilings and connect to pressure monitoring systems. these static pressure accessories vary in use from atmospheric or room pressure readings for hvac systems to cleanroom applications. static pressure pickups, sorted by material, ascending. material.
