About this file
The document is a Salient Characteristics specification for an M61A1 Gun System Ultrasonic Parts Cleaner, referenced under Technical Order 11W1-12-4-32. The ultrasonic washer must have a 3-tank system consisting of an ultrasonic wash tank, ultrasonic rinse tank, and forced air heated drying tank, with specific requirements including a minimum tank size of 36"L x 26½"W x 27"D, variable sweep frequency capability, and automatic spray features. The cleaning process involves a precise 10-minute cycle with alternating 135-second ultrasonic cleaning and 60-second agitation/spray phases, using Brulin Formula 815GD mixed at 5 ounces per gallon of water.
Key technical specifications include temperature limitations (wash tank at 160°F, rinse tank at 140°F, drying module not exceeding 200°F), ultrasonic watt density not exceeding 40 watts/gallon, and drying accomplished by low-pressure compressed air (not exceeding 30 PSI) or lint-free cloth. The system is designed for an estimated daily volume of 5 wash cycles, with parts processed carefully to avoid tank contact and subsequently lubricated according to technical order directives. The rinse cycle is specified as 5 minutes in clean tap water, and parts cleaning is limited to 10 minutes per part, with up to 30 minutes allowed for excessively soiled gun parts.

Ultrasonic watt density shall not exceed 40 watts/gallon.
The temperature of the filtered washing and rinsing solution shall not exceed 160 °F and the self-heated, high volume air drying module using air knives shall not exceed 200 °F.
Adjustable heat and time settings for both tanks are required.
Solution of Brulin Formula 815GD, product number 301007 will be mixed in an approximate 5 ounce solution to 1 gallon of water. Set wash tank to 160 °F and rinse tank to 140 °F. If difficulties are observed, then the cleaning times could easily be adjusted. The times and settings should be repeatable and adjustable.
Cleaning Cycle. Wash processing time shall not exceed 10 minutes per part per cleaning operation, limited to 30 minutes (3 cycles) for excessively soiled gun parts per cleaning operation. Parts shall not be allowed to contact the sides or bottom of the processing vessels. After cleaning, parts should be lubricated in accordance with TO directives after processing. The cleaning cycle is 10 minutes total time with the following settings:
• 135 seconds ultrasonic cleaning.
• 60 seconds agitation/spray.
• 135 seconds ultrasonic cleaning.
• 60 seconds agitation/spray.
• 135 seconds ultrasonic cleaning.
• 60 seconds agitation/spray.
Rinse Cycle. Rinse cycle should be 5 minutes in clean tap water.
Drying. Drying shall be accomplished by subjecting components to a blast of prepared dry and clean low-pressure compressed air not to exceed 30 PSI or by wiping surfaces of components with a clean, dry lint-free cloth, MIL-C-85043.
• Tank size: 36”L X 26 ½”W X 27”D at a minimum.
• Require 3-tank system: ultrasonic wash (agitation), ultrasonic rinse (heated rinse), and forced air heated drying tank.
• Require automatic spray features.
• Estimated daily volume: 5 wash cycles a day.
