Graver Technologies provides filtration products for industrial filtration, separation, and purification. The company also offers services to support its products and ensure that systems are operating at peak efficiency.
The Colorado Department of Public Health and Environment Water Quality Control Division has approved Graver Technologies QCR, QMA and ZTEC-B cartridge filters for Giardia lamblia and Cryptosporidium removal in potable water treatment.
Air Filtration
Graver Technologies designs and manufactures products to facilitate and enhance separation, purification, and process filtration. They offer solutions that remove impurities and contaminants from liquids, gases, and compressed air. Their products serve the industrial filtration, separation, and purification needs of companies worldwide.
Gravers air filtration systems use impaction and interception to reduce particle content. Using a mesh-like filter medium with fine openings, air is drawn through the device and the unwanted particles are sieved out by the filter. Particles that are too large for the openings will crash into and be directly captured by the filter fibers, removing them from the airflow.
Other types of air filtration include coalescers and vane separators, which use static mechanical devices to separate droplets from the airflow. Coalescers are designed to capture small water (and salt aerosol) droplets and make them form larger drops, while vane separators take advantage of inertia to remove droplets from the stream without affecting the flow.
Water Filtration
One of the first requirements for any civilization to thrive is a reliable source of fresh water. With natural sources being stretched by over-demand, new graver filtration technologies are being developed to meet the challenges of our times.
For example, acoustic nanotube technology uses acoustics instead of pressure to direct water molecules through carbon nanotube membranes that are just one atom thick. This allows the passage of water but blocks contaminant particles and ions. This type of filter could revolutionize the water industry and make freshwater available to billions of people in an era where global droughts threaten to cause serious food shortages.
Other types of filtration technology include reverse osmosis and template assisted crystalization, which address hard water issues without the use of salt. Both ion exchange and ultrafiltration are effective at reducing chemical contaminants in water, such as ions of calcium and magnesium, heavy metals (such as lead, arsenic, cadmium, selenium and chromium), some radioactivity, nitrates and other organic chemicals.
Liquid Process Filtration
Filtration is a simple process of passing liquid through a filter medium that blocks and captures solid particles, impurities and contaminants. It is a fundamental unit operation widely practiced throughout the chemical process and petroleum industries.
The solids removed from liquid process streams vary in size, from molecular-size contaminants to those that are visible to the naked eye. The nature of the liquid, the flow rate and the desired removal of solids determine the filter rating required for a specific application.

Filter Housings
Graver Technologies makes things to help clean and filter things.. Its product portfolio includes air and liquid processing filtration solutions. The company serves customers globally. Its air filtration systems eliminate impurities and contaminants from the workplace, increasing efficiency. Its other products include ion exchange resins, metal adsorbents, and liquid filters.
The company offers a variety of filter housing designs. The correct design depends on several factors, including the operational environment and filter or bag specifications. These include size, operating pressure, flow rate, filtration rating, and mode of operation.
TripleAir filter housings are manufactured to the tolerances demanded for critical filtration components. These are rigorously tested to ensure the required leakage classes. They are also designed to provide maximum performance and reliability. They are available in a range of sizes to suit all types of liquid applications. Safe change units are ideal for exhausting air in Biosafety Laboratories, Hospitals and other applications where contamination-free filter changes are a priority.
