Air Pressure Solutions for Seeding/Planting Machines

Since the 1950’s, the pneumatic air seeder/planter has been used as the most efficient, reliable, and cost-effective method of planting a variety of seeds. Moreover, having accurate and dependable controls are a key component to running the correct vacuum pressure for these seeding machines. Here’s how it works: using a high capacity fan, a vacuum is created in the central distribution chamber. The seeds and/or fertilizer are then pulled behind the grain drill in a separate cart. The vacuum carries the seed through tubes located under the hoppers. Seed and fertilizer are then carried in the vacuum air stream to row openers on the drill and then into the soil.

What are Room Pressure and Room Status Monitors?

Differential pressure between two rooms prevents dust, particulates, and pathogens from entering or exiting one room and going into the other. Depending on the relationship between rooms, one room will be under positive pressure when referenced against the other. This positive-negative pressure relationship between two spaces is the main idea behind clean rooms and isolation rooms. To ensure the differential pressure relationship is maintained, a measuring device must be used.

Magnehelic® Gages Monitoring Isolation Room Pressure

Room pressure monitors and room status monitors measure, display, and transmit the differential pressure reading between two rooms. In general, room pressure monitors only monitor differential pressure. On the other hand, room status monitors monitor differential pressure and additional parameters such as relative humidity, temperature, air change, or door status. They are both used in critical applications that require critical low differential pressure relationships.  Continue reading “What are Room Pressure and Room Status Monitors?”

During the Pandemic: A Study of School Air Management

Partially or completely closed school facilities have been the reality of many school corporations and families across the country since we were struck by the COVID-19 pandemic. It has effectively targeted our preparedness; changing how we view building’s HVAC systems, indoor air quality (IAQ), and even how parents and teachers view which schools are the safest, best institutions for themselves and their families.
