Which 3M Versaflo motors work with the S-133L-5?

The S-133L-5 is compatible with 3M Versaflo TR-300, TR-300N+, TR-600 series, and TR-800 series PAPR motor units. It connects via the standard 3M Versaflo breathing tube system.

Is the S-133L-5 a single hood or a 5-pack?

The S-133L-5 is sold as a 5-pack — five individual hoods per order. This makes it cost-effective for facilities managing multiple workers or high-turnover replacement programs.

What size is the S-133L?

The S-133L is the large size variant. For small or medium fits, order the S-133S-5 (small/medium 5-pack). Confirm sizing using 3M's Versaflo sizing guide before ordering.

What is the difference between the S-133 and S-433?

The S-133 is the entry-level hood without an integrated head suspension system. The S-433 series adds an integrated suspension for a more secure, adjustable fit. The S-133 is appropriate for intermittent use or cost-sensitive programs; the S-433 is recommended for all-day wear.

Does the S-133L-5 include the breathing tube?

No. The breathing tube (BT-30) must be purchased separately. The hood connects to the BT-30 tube, which then connects to the Versaflo PAPR motor unit.

Can I use the S-133L with a TR-800 motor?

Yes. The S-133L is compatible with the TR-800 series in addition to TR-300 and TR-600 motors. Verify the connection configuration with the specific TR-800 kit you are using.

How often should I replace the S-133L PAPR hood?

Replace the S-133L when it shows visible contamination, physical damage, or degradation of the fabric or visor. For facilities with regular exposure to particulates or chemical splash, weekly replacement is common. The 5-pack format accommodates weekly replacement budgets.

Is the S-133L fabric low-linting?

Yes. The S-133L uses a low-linting fabric specifically chosen to minimize particle shedding — important in pharmaceutical, food processing, and clean manufacturing environments.

What is the field of vision like in the S-133L?

The S-133L features a wide lens panel providing broad horizontal visibility. It is broader than many hard-helmet mounted visors, making it suitable for tasks requiring wide situational awareness.

Does the S-133L protect against chemical splash?

The S-133L provides coverage against light particle and mist contact. For direct chemical splash protection, evaluate the chemical resistance of the fabric against your specific hazard. For full splash protection, a chemical-resistant hood or suit may be required.

What is the weight of the S-133L PAPR hood?

The S-133L is a lightweight soft-fabric hood — significantly lighter than hard helmet assemblies (M-405/M-407). Exact weight per 3M specification sheets; contact 3M or WC Safety for current spec data.

Where can I buy the 3M Versaflo BT-30 breathing tube to use with the S-133L?

The BT-30 breathing tube is available separately through WC Safety. See 3M Versaflo BT-30 Breathing Tube in our PAPR accessories.

3M PAPR Hood Respirator Hood S-133 TR-300 TR-600 Versaflo

Short answer: the 3m versaflo s-133l-5 papr hood 5-pack is covered below on the specifications its own listing publishes, the standards it is certified to, and who it suits.

WC Safety Editorial Pick: The 3M Versaflo S-133L is the entry-level soft hood for the entire Versaflo PAPR ecosystem — the most economical way to add head, face, and neck coverage to your existing TR-300, TR-600, or TR-800 motor unit.

The 3M Versaflo S-133L-5 is a 5-pack of entry-level PAPR hoods designed for use with 3M Versaflo TR-300 series, TR-600 series, and TR-800 series powered air-purifying respirator motor units. The S-133L provides head, face, neck, and shoulder coverage using a soft, quiet, low-linting fabric — appropriate for environments where sparks, grinding debris, or paint overspray present a skin contamination risk alongside the respiratory hazard. Each hood connects to the Versaflo PAPR motor via the BT-30 breathing tube or system-appropriate connection.

The S-133 designation places this hood in the entry tier of the Versaflo S-series — it provides basic coverage without the integrated head suspension system found in the S-433 models. For workers who wear the hood intermittently or in environments where the primary need is respiratory protection (rather than all-day ergonomic comfort), the S-133L delivers the essential protection at the most cost-effective price point in the S-series lineup. The 5-pack format suits facilities managing a pool of respirator units where hoods are replaced weekly or after specific tasks.

The 'L' in S-133L denotes the large size, appropriate for most adult workers. Facilities with a mixed workforce should confirm sizing against 3M's Versaflo sizing guide. The S-133L is compatible with the BT-30 breathing tube used across the Versaflo PAPR platform, and it maintains compatibility when upgrading from a TR-300 to a TR-600 or TR-800 motor unit — making it a durable cross-platform choice for facilities with mixed PAPR motor inventories.

3m versaflo s-133l-5 papr hood 5-pack — what the listing actually specifies

Key Features

An air-purifying respirator filters air, it does not supply any. Under 29 CFR 1910.134 no air-purifying respirator may be worn in an atmosphere that is IDLH or oxygen-deficient (below 19.5% oxygen). Those conditions require a supplied-air respirator or an SCBA, and no filter or cartridge rating changes that.

Very nice

This is so much easier and nicer to wear than the helmet. The helmet is very heavy and bulky.With this, it is very light weight and very comfortable to wear. I definitely recommend getting this.
