About this file
This file is a Questions and Answers document addressing contractor inquiries regarding aircraft parts washer servicing requirements for solicitation FA558726Q0025, a Blanket Purchase Agreement (BPA) for parts washer supply and maintenance services at RAF Lakenheath and RAF Mildenhall in the United Kingdom.
The Q&A clarifies technical specifications for seven specific parts washing machines located at various squadron shops (48 CMS Shop, 48 EMS Wheel and Tire Shop, 48 AGE, 48 MUNS Armament Shop, 48 MUNS MSEM Shop, and 100 MXS). Key clarifications include: confirmation that an M810 parts cleaner with Samsol solution may serve as an acceptable equivalent to MIL-PRF-680 cleaning specifications; identification of the Safety-Kleen Model 81 Parts Washer with an approximately 302.8-liter tank capacity that requires servicing only by Safety-Kleen personnel per the operator's manual; confirmation that the Finnsonic SPINTEC 125 (450-liter heated system) operates at up to 60°C/140°F with a spray system and currently contains no chemical arrangement; and specification that the StingRay Manufacturing Wheel Washer's exact model number and capacity require government confirmation. The government provided technical operating parameters from TO 11W1-7-17-2, including maximum temperature and pressure specifications (200°F and 80 PSI respectively) and process time limits (not exceeding ten minutes) for jet washing machines. All services will be performed in the United Kingdom at the designated squadron locations on both RAF bases.

| 1 | 48 CMS | We request clarification regarding PWS 1.3.1.2 (300-liter capacity parts washing machine). The PWS specifies servicing with MIL-PRF-680 Type II or Type III, or a suitable supplement as determined by the 48th CMS Propulsion Flight. From one of our partners, the proposed equipment supplier advises that a solvent-based cleaning process is required and proposes an M810 parts cleaner using Samsol, which they state complies with the MIL-PRF cleaning specification. Can the Government confirm that an M810 parts washer with Samsol cleaning solution would be considered an acceptable equivalent for this requirement? | |
| 2 | 48 EMS | The StingRay Manufacturing Wheel Washer is identified as "[Already In Place]". Could the Government please confirm the model number and tank/fluid capacity of the existing unit? Information available publicly indicates that StingRay Aircraft Wheel Washers are available in multiple sizes (approximately 492L, 680L and 1325L capacities), and confirmation of the installed unit would assist in determining the appropriate service requirements and chemical quantities. | |
