operating a compressor in a fouled condition. We have engineered and manufactured wash oil and water injection systems for more than 10 years. Both systems inject liquid between the diaphragms in a compressor casing to reduce or eliminate fouling. An oil wash dissolves foulant and protects the internal compressor components from foulant buildup. A
