Gouri Engineering Pvt. Ltd.

Fogging and Spraying Machines
We are among the leading companies engaged in designing and manufacturing of fogging machines and spraying machines that includes misting fogger machines, mist generators, surface disinfection equipment and many more. These are used for fogging, spraying and misting purposes in pharma, food, biotech, life sciences & healthcare industry. We manufacture these as per ISO standards and test these stringently on various parameters before supplying to the clients. Our huge range comprises:


Fogger Machines
Fogger Machines

We manufacture and designe pneumatically operated fogger machines (Microfog Au – 5 & 20 liter capacity). This is a unique & detachable accessory useful for those using AVTech-DSUTM or AVTech-CWSTM sprayer units. They need not go for a separate fogger unit for aerial fogging. The fogger works silently laminating noise pollution.

FOGGER ATTACHMENT is manufactured in special grade non-magnetic stainless steel. The gaskets, ‘O’ rings, suction & discharge pipes used are of medical grade silicon material.  The complete hardware is of stainless steel. 

The device is simple and can be mounted on the sprayer unit through Quick Release Coupling of stainless steel. Thus a single sprayer unit is now converted to Fogger unit within seconds. This proves cost effective eliminating additional inventory. 

THE FOGGER ATTACHMENT is autoclavable repeatedly @ 120oC. 

This fogger attachment is handy & useful to pharmaceutical, biotech industry, research laboratories in life science establishments working on delicate animals that are sensitive to sound levels beyond 30 TO 40 dB.

Electric Fogger

We manufacture and design electric fogger. Also known as electrically operated fogger machines (Nanotek® & Micro Mist®).

Micro MistTM & NanotekTM: This state of the art dedicated aerosol generator for aerial sterilization is extremely popular among Pharma-food-Biotech & Healthcare sectors, life sciences & tissue culture industry. Where our esteemed competitors claim a droplet size generated as 10 to 20 microns (but not validated for the droplet size) Micro MistTM & NanotekTM generate droplet size in “Sub-Microns”. This claim is supported by a complex test conducted by globally renowned research institute in India & test-results are declared to this effect. Perhaps this is the only fogger available globally generating droplet size in sub-microns.

This is a dedicated fogger that operates on single phase 240 Volts 50Hz power supply & is recommended for clear aqueous formulations having density of 1.05 max. For liquids with higher density & viscosity a customized fogger can be supplied.

A 5 liter capacity tank manufactured out of special grade stainless steel is perfectly compatible to disinfectants having pH from 1.5 to 14. Thus one can use acidic as well as alkaline formulations without being worried on the corrosion & erosion of the metal.

APPLICATIONS:

Micro MistTM & NanotekTM are dedicated foggers for aerial sterilization using aqueous disinfectants. Very fine droplets form clouds that fill the closed room and impart 100% efficacy bringing microbial load to almost zero. The fine fog penetrates into difficult to approach areas, crevices in the furniture & plaster, gaps behind the panels and cupboards and eliminated the bacterial load. 

Absence of floor wetting effect:

The fine fog gets uniformly distributed & settles on walls, ceilings and the other surfaces making them free of contamination.  Thus MICRO MIST fogger does aerial as well as surface disinfection. These fine droplets evaporate quickly without causing wetting effect & are popularly termed as “dry fog”.

Micro MistTM & NanotekTM take care of 5000 to 6000 Cft volume in single charge depending on the humidity Vs temperature conditions from place to place.

MOC: All wetted parts as well as complete hardware is in best grade stainless steel. 100% components are free of corrosion/erosion eliminating the risk of damage from sultry weather / chemicals etc. All other materials are inert to low pH disinfectants.

A tailor made high powered, high efficiency drive motor is incorporated which sustains large voltage variations. Motor & timer-switch  used are UL & CE marked.

AFTER SALES SERVICE: Micro MistTM & NanotekTM are simple user-friendly machines and are free of maintenance. In the event of any problem, service / replacement is assured within 48 hours of reaching the fogger at our works.

The foggers are available off the shelf at highly competitive quotes.
