Air Purification

The engineering team at Graver Technologies can custom design air purification solutions that meet the demanding requirements for air purification applications.

Engineered Filtration Solutions for Original Equipment Manufacturers

Whether it is a medical device, cabin air filter, room air purification, or an industrial vacuum, original equipment manufacturers of air purification equipment often require custom filtration solutions to meet performance or other design requirements. The equipment may require high-efficiency particulate air (HEPA) designs, activated carbon or adsorbent media for the removal of odor, toxic fumes or gases, or unique dimensional or material specifications. Design, prototyping, testing, and manufacturing expertise are essential to delivering a product that performs to both performance and quality specifications while meeting the economic expectations of the consumer. Graver Technologies has a long history of developing innovative custom solutions for OEM manufacturers in some of the most demanding air purification applications.

Frequenty Asked Questions

How often should gas turbine filters be replaced?

This depends on the environment and filter type; however, pre-filters are changed every 3–6 months, while final filters may bechanged once in a year or two. Monitoring pressure drop is key to determiningreplacement timing.

What factors affect the operating life of a gas turbine filter?

Here are some factors:

Ambient dustand pollution levels
Operatinghours and load
Pulse-cleaningfrequency, depending on the type
Humidity andmoisture
Filter mediaand design

How do I know when a filter needs to be changed?

Differential pressure across the filter is animportant aspect in this case. If it increases beyond the set threshold, thefilter may be clogged or need cleaning or replacement.

What is pressure drop and why does it matter?

Pressure drop is the resistance to airflow through afilter. A high-pressure drop reduces turbine efficiency and increases energycosts. Selecting low-resistance filters helps improve performance.
