You can use a shop vacuum as an air pump by converting its exhaust function. Here's how:
Using a Shop Vacuum as an Air Pump
Instead of an air compressor, a shop vacuum can be used to inflate items like air mattresses or pool toys. This requires a simple modification of your shop vac:
Step-by-Step Guide:
- Prepare a Connector: Find a plastic squeeze bottle and remove its top. This top will serve as an adapter.
- Attach the Connector to the Vacuum Hose: Fit the bottle top securely onto the hose of your shop vacuum. You may need to use duct tape to ensure a snug, airtight seal.
- Connect to Exhaust Port: Attach the modified hose to the exhaust port of your shop vacuum. This is the port from which air is expelled, not where it's sucked in.
- Inflation: With your modified hose attached to the vacuum’s exhaust, direct the airflow into your inflatable item.
Additional Tips:
- Secure the Seal: Make sure the bottle top is securely attached to the vacuum hose to prevent air leaks and maintain pressure for inflation.
- Duct Tape is Your Friend: Use duct tape liberally for a strong seal, especially if the fit isn’t perfect.
- Observe Carefully: If the vacuum hose has a small diameter and you are trying to inflate a large item, be patient and keep monitoring to ensure you don't overheat the vacuum or damage the inflatable.
Why use a shop vacuum as an air pump?
- Convenience: If you lack a traditional air pump or compressor, a shop vacuum can be a suitable alternative.
- Cost-Effective: It saves you from needing to purchase a dedicated air pump.
- Versatility: Shop vacuums often include different nozzle attachments, allowing you to potentially adapt to various inflatable sizes.
By following these steps, your shop vacuum can successfully act as an air pump to inflate various items.
