The aim is to equip readers with the knowledge to select one of the best air compressors for winterizing RVs, ensuring a hassle-free and effective winterization process.
Tank Size and Airflow (CFM)
Tank size, measured in gallons, dictates how much compressed air is stored and readily available. For RV winterization, a larger tank generally provides a more consistent and prolonged airflow, reducing the need for frequent compressor cycling. A tank size of 3-6 gallons is generally sufficient for smaller RVs with limited plumbing, while larger RVs with extensive systems might benefit from a tank size of 6-10 gallons or more. Choosing a tank size should be balanced against portability, as larger tanks often translate to increased weight and bulk, which can be a concern for storage in an RV.
Airflow, measured in Cubic Feet per Minute (CFM) at a specific pressure (PSI), is the rate at which the compressor delivers air. For winterizing RVs, a CFM rating of at least 2.0 CFM at 40 PSI is typically recommended. Insufficient CFM can lead to inconsistent air pressure and require multiple passes to effectively clear water from the plumbing. It is important to note that the advertised CFM rating is often the “displacement” CFM, which is higher than the actual CFM delivered. Always look for the “delivered CFM” rating to get a more accurate indication of performance. Moreover, RV antifreeze typically requires lower pressure than water, but a compressor that can handle a decent CFM at 40 PSI will likely be able to effectively use RV antifreeze as well.
Portability and Size
Portability is a crucial consideration for RV owners, given the limited storage space and the potential need to move the compressor around the RV park or storage location. Smaller, lightweight compressors are easier to transport and store, making them a more practical choice for many RVers.
