Introduction
The CRAFTSMAN CMXZVBE38660 2-1/2 inch Muffler Diffuser is an accessory designed to enhance the functionality of compatible CRAFTSMAN wet/dry shop vacuums. This attachment serves two primary purposes: to reduce operational noise and to diffuse the airstream from the vacuum's blowing port. By diffusing the exhaust air, it minimizes the scattering of debris and dust, contributing to a cleaner work environment. Its industrial-grade construction ensures durability for various applications in homes, garages, basements, and workshops.
Safety Information
Always read and understand your wet/dry vacuum's instruction manual before installing or operating any accessories. Ensure the vacuum is unplugged from the power source before attaching or removing the muffler diffuser. Use appropriate personal protective equipment (PPE) such as eye protection and hearing protection during operation. Do not modify the diffuser or use it for purposes other than its intended design.
Setup
1. Unpacking and Inspection
Carefully remove the muffler diffuser from its packaging. Inspect the attachment for any signs of damage or missing components. If any damage is found, do not proceed with installation and contact CRAFTSMAN customer support.
2. Compatibility Check
This muffler diffuser is designed for CRAFTSMAN wet/dry vacuums with a 2-1/2 inch blowing port. Verify that your vacuum model is compatible. Compatible models include, but are not limited to: CMXEVBE17040, CMXEVBE17925, CMXEVBE17584, CMXEVBE17590, CMXEVBE18590, CMXEVBE18690, CMXEVBE17155, CMXEVBE17594, CMXEVBE17595, CMXEVBE17606, CMXEVBE17607, CMXEVBE17596, CMXEVBE17656, CMXEVBE18595, and CMXEVBE18695.
3. Installation
- Ensure your wet/dry vacuum is turned off and unplugged from the power outlet.
- Locate the blowing port on your CRAFTSMAN wet/dry vacuum. This is typically a circular outlet on the motor head.
- Align the muffler diffuser with the blowing port. The diffuser features a locking mechanism for secure attachment.
- Push the diffuser firmly onto the blowing port until it clicks into place, indicating a secure connection. Ensure the locking tab is engaged.
Operation
Once the muffler diffuser is securely installed, you can operate your wet/dry vacuum as usual. The diffuser will automatically begin to reduce the noise level and spread out the exhaust air. This is particularly beneficial when using the vacuum in enclosed spaces or when blowing debris, as it prevents concentrated blasts of air from scattering dust and light materials.
Benefits of the Muffler Diffuser:
- Quieter Operation: Helps to dampen the sound produced by the vacuum's exhaust, making your work environment more comfortable.
- Reduced Blowback: Spreads the exhaust air over a wider area, preventing a strong, direct blast that can stir up dust or move objects you don't intend to.
- Versatility: Ideal for use in various settings, including workshops, garages, basements, and even for detailing vehicles.

Maintenance
Regular maintenance of your muffler diffuser ensures optimal performance and longevity.
- Cleaning: Periodically remove the diffuser from the vacuum and tap it gently to dislodge any accumulated dust or debris. For a more thorough cleaning, you may rinse it with water and allow it to air dry completely before reattaching.
- Inspection: Regularly inspect the diffuser for any cracks, tears, or excessive wear. If the internal foam or plastic housing is damaged, replace the diffuser to maintain effective noise reduction and airflow diffusion.
Troubleshooting
Issue: Diffuser does not fit securely.
- Solution: Ensure your vacuum has a 2-1/2 inch blowing port. Verify that the locking tab on the diffuser is properly aligned and engaged with the vacuum's port.
Issue: Noise reduction or airflow diffusion is ineffective.
- Solution: Check the diffuser for excessive dust buildup or damage to the internal foam. Clean or replace the diffuser as necessary. Ensure the diffuser is fully seated and locked onto the blowing port.
