Downdraft Table Applications

Downdraft Table Application

There are many manufacturing processes that require human operators to perform tasks, which can create hazardous levels of particulate, fumes, gases, vapors, and mists. A few of these processes include: welding, sanding, grinding, brazing, laser cutting, tempering, and quenching. The Occupational Safety and Health Administration (OSHA) has regulatory requirements to reduce worker’s exposure to these hazards, which can cause respiratory and other health issues. Downdraft tables are workstations designed to better protect the operators who perform these tasks, in a bench top setting, by removing the hazardous material that laden the air from the worker’s breathing zone.

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?”

Level Detection of Powder & Bulk Solids

Level detection applications are one of the most interesting things we do at Dwyer as there are so many types of switch technologies. Even just for powder and bulk level detection, there are many ways to sense the level. Dwyer offers several different technologies for powder and bulk solids point level detection. These include: diaphragm, paddle, tilt, capacitive, and vibration. So if you’re wondering how to determine which technology is best for your application, here is a simple guide to help you select the proper technology.

Importance of Sensor Stability in Healthcare Isolation Rooms

Magnehelic® Gages Monitoring Isolation Room Pressure

The purpose of a healthcare isolation room is to prevent patients with contagious illnesses from spreading to others or to keep immunocompromised patients safe from exposure to airborne pathogens. As such, there exist two types of isolation rooms, either positively or negatively pressurized. 

Positive pressure isolation rooms are designed to keep pathogens and outside air from entering the room, i.e. air inside the room is forced outward and is typically used for immunocompromised patients. Like clean rooms, it is important to maintain proper positive pressure within the protective isolation room to keep the patients safe.

A Dwyer Guide to the Digital Catalog

In this age of virtual meetings and online connections, to “Google” something has become synonymous with quickly looking up information. For some, bookshelves are more for decor than they are functional, and trends are leading to becoming more environmentally-friendly and saving paper. Print media is not necessarily “dead,” but it is becoming much less prevalent as we journey forward in this digital age.

When speaking on digital resources, we have to take this chance to talk about some of the benefits that our digital catalog can offer. Available on both desktop (via our website) and mobile (via the app), the digital catalog allows you instantaneous access to application guides, selection guides, and product specifications.  Continue reading “A Dwyer Guide to the Digital Catalog”
