Companion Product: Safemod / Safescan
Ultra High Efficiency Containment Filter Modules
The SAFEMOD may be changed safely with their normal changing procedure. A SAFEMOD used in conjunction with the Formaldehyde Generator/Neutralizers enables the decontamination of the installed filters prior to the opening of ductwork components, thereby enhancing safety for the maintenance personnel.
- Modular Filters for Hazardous Applications
- Handled as Completely Contained Module
- Available With Particle and Gas Phase Filters
- Factory Tested to Ensure Integrity
- Modular Construction Permits Multiple-Size Installations
Typical Installation With Multiple Modules

Formaldehyde Generator/Neutralizer General Operating Protocol (all models)
The space to be decontaminated is measured and the volume calculated in cubic feet. The space is then sealed. The relative humidity inside the space is measured or sensed, depending upon the model. The Nextek Generator / Neutralizer generator is then connected to the space with the appropriately sized connections. The humidifier, formaldehyde, and neutralizer canisters are then loaded with the proper amount of material as calculated using the formulas in the operating manual or the amount determined by other evaluations. The generators are then programmed with the operating sequence choices as determined by the operator and then started by pushing the "Start" button. The space is then conditioned to the proper relative humidity. After this is accomplished, the generator starts formaldehyde insertion. The amount of air required to insert the formaldehyde/neutralizer is circulated through the generator when the insert sequences are active. After the formaldehyde insertion cycle, the generator holds for a preselected contact time. After the contact time, the generator automatically begins the neutralizer insert cycle, inserting the neutralizing gas into the space. At the conclusion of this cycle, a preset one hour neutralizer contact cycle begins. When this is complete, the space may be reopened. The product of the reaction between the formaldehyde and the neutralizer is a white powder, which has a slight “fishy” odor. For safety, the space should be ventilated and air samples taken prior to occupancy.
Built-in safety features in all of the Nextek generators permit completely automatic operation without the necessity of a technician’s constant attention.
Nextek, LLC warrants that this instrument will depolymerize paraformaldehyde and neutralize formaldehyde in the contained space, when it is used according to the operating instructions provided. No warranty is made, expressed or implied, concerning the biological decontamination of any spaces.
