• The ROOTS™ URAI-G™ are heavy-duty air blowers that have been designed with mechanical seals for gas applications. They utilise mechanical seals (instead of typical lip seals) to minimise gas leakage into the vented oil-bearing chambers.
• The compact, sturdy design is engineered for continuous service when operated in accordance with speed and pressure ratings
• They are available in 12 different models which feature the ‘universal’ mounting feet which allow them to be mounted in four different configurations.
• The unit is centre-timed so that it may be operated in either direction. The unit features grease lubrication on the drive end and oil lubrication on the gear end.
• Each unit is mechanically tested and given a 15 psig static leak test. A 1/8” (0.3137 cm) NPT purge port is provided at each seal for buffer gas application as required.
• ​Since 1854, Howden has been continuously manufacturing and developing the rotary positive displacement air blowers under the industry-respected name ROOTS™.
