Bulk Bag Fillers

The NT Series offers sturdy arms for looped bag handles that can be easily hung, while the bag filling machines in our Heavy-Duty Series are designed with sliding hooks for quick loading of empty bags and safe unloading of full bags. Both models come with Hapman’s exclusive inflatable bladder design for a dust-tight seal during the bulk bag filling process.

• Bulk bag filling systems are fed either directly from equipment or from a feed conveyor.
• The empty bag is placed on the secure arms (NT Series) or on the lift hooks (Heavy-Duty Series) of the bag filling machines.
• The bag spout is placed over the bladder.
• The filling button is activated to begin the filling of the bladder.
• Once the bag is securely in place, material can begin to flow into the bag.
• When the bag is full, the release button is pressed, allowing the bladder to deflate.
• The filled bag can then be removed from the filling station.

• Hapman’s bulk bag filling machines handle various bag sizes up to 4,000 lbs (1,814 kg).
• Engineered, dust-tight bladder filling mechanism on both the NT Series and Heavy-Duty Series bag filling machines for maximum dust control.
• Cantilevered, heavy-gauge steel tubing frame with adjustable or fixed height for unrestricted bag access from three sides.
• Forklift pockets for easy movement.

Heavy Duty Series Bulk Bag Filling Machines 

A. Pneumatic controls – Easily accessible for efficient bag change out.

B. Traversing and quick-releasing rear hook assemblies – Rear hooks can travel to the front of the filler. This allows for easy staging of the bag and allows the operator to release the rear straps from the front of the frame when the bag is filled.

C. Screw jack and powered carriage – The screw jack raises and lowers the bag carriage to accommodate different size bulk bags while allowing bags to be staged at an operator-friendly height. The powered carriage allows the bag to be filled while hanging and then lowered to the pallet, resulting in a bulk bag that is more stable because it has a properly filled base. This fill method also safeguards your operators from drop hazards associated with suspended hanging/filling systems.

D. Venturi bag inflation/deareation option – The Venturi allows the operator to inflate the bag easily for filling with desired material. It will then work as a deaerator when the bag is filled.
