RAM Heavy Duty ECO+ Bags 7 ft x 4 ft
These RAM ECO+ bags measure 7 feet by 4 feet and are designed for removing loose-fill fiberglass, cellulose, or rockwool insulation from attics or walls. They hold up to 88 cubic feet or about 400 pounds and are made from 2.4 fabric-strength 100% XHD polypropylene. The bags provide a safe containment method to collect debris and make disposal easier. They are compatible with typical insulation vacuums, and their large size helps reduce bag changes on bigger jobs.
RAM Heavy Duty 6 ft x 4 ft Bag
This RAM bag measures 6×4 feet and is designed to hold approximately 75 cubic feet of insulation debris. Constructed from a heavy-duty 2.4 non-woven polypropylene, the bag is built to resist tearing during removal work. The product is suited for direct use with many insulation vacuums or hoses, featuring a spill-safe spout and an easy-to-use fill process. Users should monitor bag fullness to avoid overfilling, which can impede mobility during cleanup.

It is positioned as a versatile option for maintenance and on-site repairs, helping to minimize downtime on professional projects.
Buying Guide
Choosing the right cellulose insulation blower machine involves balancing capacity, portability, and compatibility with your existing setup. Consider the following factors:
- Airflow and static pressure: Higher CFM and static pressure improve debris pickup and suction efficiency, especially in attics with dense cellulose.
- Electrical requirements: Verify voltage, phase, and amperage to ensure safe, reliable operation in your workspace.
- Portability: Heavier machines may require wheels or casters for attic access; lighter units offer easier transport but may have lower capacity.
- Bag and bagging options: Durable bags reduce mess and disposal hassle; ensure compatibility with your vacuum or hose size.
- Replacement parts availability: OEM or widely compatible blowers help minimize downtime due to worn components.
- System compatibility: If integrating with an insulation removal setup, confirm inlet/outlet sizes and mounting compatibility with existing vacuums or blowers.
- Durability and build quality: Aluminum end shields, robust impellers, and sturdy housings contribute to longer service life in rugged job sites.
- Maintenance requirements: Look for easy access to filters, impellers, and motors to simplify routine service.
When comparing options, assess how each blower and accessory aligns with your typical project scope—whether you handle occasional attic cleanouts or ongoing insulation removal contracts. This ensures you invest in equipment that delivers consistent performance, reduces downtime, and meets safety standards on American work sites.
