Mert Littlefield Blowers
Don', Hampton Blowers

The Blower Shop, when Al Hoffman was alive
(IIRC) at the time they were the only people still
(Now a few do, INDY is one)
making a blower manifold, with a pop-off valve for a RB/B engines
'not the burst plates'
(if you ever run it in the cold you will wish you had one)
But all the above have or had great blowers/roots style
may different rotor angles & sizes etc.
most all of the org. founders are no longer with us
either family or another ownership completely etc. now
I used to use a shitload of Mert Littlefield blowers (top-notch)
they were in SoCal too, so my shipping
or my ability to go down & pick stuff up was way easier, & cheaper
over the years, 6:71-8:71 to 10:71-14:71,
from 10% undriven to 50% overdriven in either 8mm or 3"
they ain't cheap, don't even attempt to bargain shop there
mostly for racing, Methanol (or Nitro) 'lots of boost',
not much streetcar wise, take a lot of power to spin them
hard anodized cases & timed/hardened gears, Hi-helix rotors &/or Teflon strips,
better billet materials
but it was/still is the quality stuff
good Luck

What Is a Roots Blower?
A roots blower is primarily utilized for air blowing, achieved by rotating a pair of blade-shaped rotors.
These blowers typically consist of 2 to 4 blades. The greater the number of blades, the more air can be blown per rotation, thus enhancing efficiency.
The rotor shapes are broadly categorized into involute, cycloidal, and envelope types.

Uses of Roots Blowers
Roots blowers find their application in several areas:
- Water Treatment Facilities
They are employed in septic tanks at water treatment facilities in various institutions like factories, schools, hospitals, etc., for aerating the tanks. - Industrial Vacuum Cleaners
Roots blowers are integral in vacuum cleaners and dust collectors used in factories for suctioning dust and air, and subsequently exhausting purified air. - Vacuum Trucks
They are used in vacuum trucks for suctioning sludge and debris in cleaning operations. - Welding Fumes Extraction
In factories, they are used in industrial vacuum cleaners to extract fumes generated during welding and capture them in filters. - Air Blowing in Factories
Employed in powering air blowers for removing moisture from products in manufacturing settings.
Principles of Roots Blowers
Roots blowers are designed with a housing body featuring an intake hole and an exhaust hole. Rotors within the blower draw air in through the intake and expel it through the exhaust. During operation, a small gap is maintained between the rotor and the housing, as well as between the rotors themselves, ensuring that they rotate without making contact.
The rotation direction is from the intake chamber to the exhaust chamber, pushing air from the intake to the exhaust. The efficiency of the blower is higher when the gap between the rotor and housing, and between the rotors, is narrower, as this minimizes leakage.
However, an overly narrow gap can risk rotor lock due to foreign objects entering the housing, leading to rotation failure. Therefore, the choice of Roots blower should consider the cleanliness of the operational environment.
Roots blowers are predominantly used in two or three-blade configurations. The two-blade type discharges air four times per revolution, while the three-blade type can discharge six times per revolution, enhancing efficiency but also increasing costs due to the complexity of rotor machining.
