Surface Finishing

Graver Technologies multifunctional adsorbent products are more effective than PAC (powdered activated carbon) in removing many contaminants.

Innovative Technologies Products for Surface Finishing

The plating process includes several steps that require considerable pretreatment, treatment, and post-treatment steps. Whether the process is plating chrome, zinc, copper, gold, or another material, the treatment provides many benefits to products made from metal and other materials, from decorative appeal to improved surface hardness to improved corrosion resistance. Creating a high-quality finish requires effective removal of contaminants from finishing solutions, whether managing airborne particles, debris from machines or manufactured parts, or the effective control of organic impurities. Graver Technologies provide filtration and purification products that can effectively address bath contaminants through the acid and alkaline cleaning, rinsing, plating, and waste treatment processes.

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.
