The Groz Air Lubricators with Metal Bowl feed lubricators feed lubricants to pneumatic equipment with a constant oil-to-air density over a wide range of flow. These lubricators are Fog/Micro-mist type up to 50 feet pipe runs. Both the head and bowl are made from die-cast aluminum. This head is fitted with Oil drop indicator, Oil drop controller, and Oil filling plug.

Having a metal bowl makes these air lubricators good in environments such as chemical plants, paint shops, pharmaceutical plants, and foundries where the air may contain chemicals such as acetone, benzene, kerosene, gasoline, carbon tetrachloride, ethylene dichloride, and toluene. These air lubricators are also good for high pressure use as well as with air compressor systems using fire resistant lubricants.
