This class of air nozzles is expressly designed for the various Air Blowing applications using compressed air or technical gas fluids for cooling and manufacturing operations and are available in many different versions about performances, thread sizes, materials, air flow-rates, regulations compliant as EC n.1935/2004, EU 10/2011, FDA reg.21 CFR, OSHA, DIN EN ISO 9612.
The Spraytecs Air Nozzles BW series for compressed air are specialized in CNC machine tools cooling, to substitute (or to add a great improving to liquid cooling system)) with a concentrate compressed air cooling system the existent liquid cooling system during high temperatures reached during the machining operations, as milling, cutting, drilling, surfaces grinding, tools sharpening, routing and tires grinding.
Spraytecs main design target is the constant increasing of tool life due to the lower working temperatures and a low quantity of compressed air to do it, with as direct consequence a great save of money in the CNC machine tool total working costs on yearly basis.
Compressed air pressures in the range 2 bar/8 bar (30 psi/120 psi) give great cooling results with the right installation nozzle set solutions, in the larger number of machine tools.
There are several advantages to consider the substitution of the existing liquid cooling wit a compressed air cooling in your CNC machines:
- all machined parts are absolutely clean and dry when come out your machine
- no need, no costs for machined and human operations to clean and dry the just manufactured parts, therefore they are immediately available to be packaged and shipped
- two big tools manufacturers declares that CNC air cooling means save 15% manufacturing global costs
- no dirt, bad smell and corrosive action in the CNC, machined materials, ground, walls, clothes
- no spaces, recipients, dedicated machines to manage and stock new and exhaust coolants
- no dangerous vapors, fumes or coolant contacts with operators, improving work conditions
- more value for your cleaned scraps/chips amount when you will sale it
- no risks and production delays/damages for cooling system default, because there are no parts with possible wearing
- no toxicity in coolant fluid, no water needed, air is an environment friendly solution
- high energy to extract out the chips from the way of the machine tool cutter
- focused compressed air to eliminate the Shock Cooling micro-crackings generated by water thermal inertial effect in carbide tools, extension of cutting tools life
- small amount of compressed air to obtain great cooling results
However Spraytecs suggest that every machine tool must be tested on what kind of materials, machine tools and machining operation can be performed at the best with air cooling or other cooling solutions.
Materials and production are all strictly of West Europe origin, with certificates available. In every nozzle are below shown what standard rules meet.
BW18A - Air Impact Nozzles
These general purpose cooling nozzles are suitable where a concentrate air beam must hit with energy a small area. Typical application is the cooling of very hot materials surfaces, vanes and holes, as metal alloys, aluminium, magnesium alloys, etc.
These air nozzles have a low air consumption, and meet the EU Machine directive, the OSHA maximum allowable noise exposure standard 29 CFR 1910.95 (a) and are suitable for hard working environments with high temperatures.
Moreover are available suitable accessories as nipples and flexible-pipes of different lengths to fit at the best your cooling direction needs.

PI - Threaded Micro-Pipes
The Spraytecs Threaded MicroPipes are designed to fit the micro-nozzles and nano-nozzles in very small spaces in all machine processing contexts, from CN machine center cooling of tools from the spindle vanes, to many other precision cooling and displacement action performed with fluids.
Moreover also your R&D department could find a useful elementary component for their prototyping needs.
Our MicroPipes are available in different lenghts, thread sizes, materials, angles.

The MicroPipes are available on other materials on request.
Here below a Micro-Pipe is mounted with a Micro-Air Nozzle to reach a deep cavity in an industry process:
Micro-Pipe thread is M5, but M6 is the nipple thread on flexible pipe, therefore a Spraytecs nipple reduction M5 Female to M6 Male is shown.
Ask us for price, materials, dimensions, performances and other information about these products.
